Consider an optical system consisting of two parallel planes separated by some distance. The electromagnetic f i e l d intensity in one plane is a function of the intensity in the other plane. To produce specific intensity functions in one plane from a particular intensity function in the other requires, in general, a complex valued f i l t e r to be placed between the two. An example of such a f i l t e r i s a lens. An ideal lens can be represented mathematically as a 1 multiplicative factor of the form, exp -jc(x 2+y 2) (1) where c i s a constant and x, y are perpendicular reference axes. It is desirable to be able to produce more complicated phase functions than that of the lens. In fact, the correc- tions that must be made to a real lens so that i t approximates the ideal more closely require a much more complex phase function. 2 A simple form of phase f i l t e r was used by Tsujiuchi to correct lens aberrations and to produce optical systems with two f o c i i . The f i l t e r s used were very simple in that they consisted only of a pattern of half wavelength retardations. Approximations were made in the calculations of the f i l t e r pattern in order to easily fabricate the devices. - 2 - Recently holographic techniques have been used to pro- duce phase f i l t e r s . 4 In the referenced work the authors used an amplitude hologram. Less than ten per cent of the signal power was deflected into the beam that has the desired altered phase.^ The most straightforward method of producing a pattern of phase v a r i a t i o n would seem to be the use of a transparent material with a pattern of thickness v a r i a t i o n . The material must have an index of r e f r a c t i o n d i f f e r e n t from the trans- mission medium so that the speed of l i g h t i s d i f f e r e n t i n the f i l t e r . Thus the thickness variations convert to phase v a r i - ations. With the aid of an index matching layer a phase f i l t e r of t his type passes a l l of the available input signal power and is thus a s i g n i f i c a n t improvement over the holographic type of f i l t e r . The thickness v a r i a t i o n type of phase f i l t e r could conceivably be used in many applications i n the f i e l d of o p t i c a l information processing and s p a t i a l f i l t e r i n g where conventional photographic holograms are now used. Researchers at I.B.M. have produced thickness v a r i a t i o n phase f i l t e r s which they c a l l Kinoforms.^ The devices are constructed by bleaching computer generated photonegatives. Bleaching removes the dark material in the negative, leaving a transparent pattern of thickness. It i s pointed out that the ideal way of fab r i c a t i n g such devices would be to produce the thickness d i r e c t l y and not r e l y on a transformation from - 3 - i n t e n s i t y to phase. In t h i s thesis an in v e s t i g a t i o n i s made of a method of fa b r i c a t i n g a two dimensional device with thickness v a r i a - tions suitable f o r use as a phase f i l t e r i n an o p t i c a l system. Starting with a p a r a l l e l faced slab or substrate of transparent material, additional material must be added or removed to produce a thickness v a r i a t i o n over the surface. Removal of material was not further explored, although developments i n l a s e r etching techniques make i t look f e a s i b l e . There are a number of methods of adding material to a sub- strate such as vacuum deposition, sputtering and screening. Of these, vacuum deposition seemed to be the most promising technique and was singled out f o r investigation. Vacuum deposition was chosen f o r further study f o r a number of reasons. The technique has been used widely i n the f i e l d of optics f o r various purposes such as a n t i - r e f l e c t i o n films and multi-layer frequency s e l e c t i v e f i l t e r s . The materials used i n vacuum deposition have been studied and y o Q -] Q are well documented. ' ' ' The following chapters describe the work performed to investigate the f e a s i b i l i t y of f a b r i c a t i n g phase f i l t e r s by vacuum deposition techniques. Chapter I i s a description of the proposed f i l t e r and the method of production. Chapter II describes the hardware designed and constructed, and the software written. Chapter III i s a summary of the re s u l t s and conclusions of the investigation. - 4 - CHAPTER I - BAC KGROUND A d i e l e c t r i c material w i l l cause a phase change of the l i g h t transmitted through i t i n the following way. Consider Figure 1(a). The o p t i c a l system between the two f i x e d r e f - erence planes ZQ and z^ can be considered as a system with a transmission c o e f f i c i e n t T. i s the Fresnel r e f l e c t i o n c o e f f i c i e n t from medium i to medium j .

Angle o f Incidence where?!is the wavelength of the l i g h t , i s the r e f r a c t i v e index of the i ^ 1 medium, and d^ i s the thickness of the i ^ 1 medium. By varying the thickness d^, the phase change i n t r o - duced by the o p t i c a l system i s altered. A s i m i l a r r e s u l t can be achieved by using the r e f l e c t i o n geometry of Figure 1 ( b ) . The o p t i c a l system between the two planes ZQ and z^ can be characterized by a r e f l e c t i o n c o e f f i c i e n t R = ( 1 +r Q 1 + F 1 2 + r Q 1 ^ 2 ) ( r Q 1 + ^ 2 e " J 2 9 1 ) ( g ) 1 + r 0 1 r 1 2 e - J 2 9 1 The computer program i n Appendix I was used to calculate the phase changes produced by varying the thickness of the d i e l e c t r i c layer. The a r b i t r a r y zero of phase change was chosen to occur when the d i e l e c t r i c layer has zero thickness. Appendix I l i s t s the computed change of phase due to d i e l e c - t r i c thickness. For the transmission geometry, the o p t i c a l constants used i n the equations were chosen f o r a f i l m of magnesium fl u o r i d e on glass i n a i r . For the r e f l e c t i o n geometry, the constants used correspond to a f i l m of zinc s u l f i d e on aha aluminum backing i n a i r . These constants were chosen because they represent materials that have been frequently used i n the f i e l d of optics. A phase f i l t e r , being a device which a l t e r s the phase of a plane wave as a function of two dimensions, could be - 8 - used i n much the same manner as an interference hologram to store information and create images. This property can be demonstrated by u t i l i z i n g the Fourier transformation property of a lens. A lens displays the two dimensional s p a t i a l Fourier transform of the i n t e n s i t y of one of i t s f o c a l planes i n the other f o c a l plane. Thus, i f an image i s placed i n the f o c a l plane of a lens, i t s Fourier transform would appear i n the other f o c a l plane. The Fourier trans- form of a r e a l image i s i n general a complex valued function. The amplitude part of such a function can be e a s i l y constructed with a photographic transparency. I f a phase f i l t e r could be constructed with the appropriate pattern of phase, one should be able to produce an image from the complex valued Fourier transform. Even without the amplitude part of the f i l t e r , i t should be able to produce a reasonable image. This experiment was simulated numerically by using the Fast Fourier Transform program available on the University of B r i t i s h Columbia I.B.M. 360 computer system. A two dimensional black-white image was d i g i t i z e d and then transformed into the s p a t i a l frequency plane. There the i n d i v i d u a l s p a t i a l frequencies were altered by normal- i z i n g each amplitude to unity while leaving the phases i n t a c t . This simulates the e f f e c t of i l l u m i n a t i n g the phase f i l t e r without amplitude compensation with a unit amplitude plane wave. The Fourier transform of the altered transform was then taken. This corresponds to the reconstruction process with a lens. Taking the Fourier transform twice, - 9 - instead, of taking the transform and i t s inverse, r e s u l t s i n the axes being inverted. The program written to demonstrate t h i s e f f e c t i s listed, i n Appendix I I . The input to the program i s the d i g i t i z e d pattern of Figure 3(a). The i n t e n s i t y function i s spread by the'amplitude normalizing. However, the bright areas, as indicated by the pattern of Figure 3(b), s t i l l show a reproduction of the o r i g i n a l . The r e s u l t s of the computer experiment demonstrate the c a p a b i l i t i e s of a phase f i l t e r . Vacuum deposition requires that the material to be deposited be heated to the vapour state and then condensed on the substrate. To produce a phase f i l t e r with vacuum techniques, involves the deposition of a varying thickness d i e l e c t r i c on the surface of a substrate such that the thickness i s a function of the p o s i t i o n on the surface. This involves c o n t r o l l i n g the p o s i t i o n of deposition and also c o n t r o l l i n g the thickness of deposition. P o s i t i o n of deposition can be c o n t r o l l e d by collimating the vapour from the deposition source into a narrow beam and exposing the substrate only to that beam. The substrate must then be moved about so that the beam covers the entire surface. Use of t h i s method r e s t r i c t s the s p a t i a l resolution to the fineness of the beam. An ellipsometer was available to measure the thickness of the deposited layer. The measurements from the ellipsometer could be used to determine the thickness of the layer that was currently being deposited - 1 0 - *"* ** ** ** ** **************** Or i g i n a l Image **************** ** ** ** ** ** * ** ** Figure 3(a) * ** * ** ** **** * * **** * * Second Transform * * * **** * * * ****. * ** ** Figure 3(b) Spatial Fourier Transform Example - 1 1 - and thus indicate when the layer was thick enough before proceeding to the next area. The ellipsometer had been previously automated by connecting i t to a D i g i t a l Equipment Corporation PDP 8-e minicomputer. This computer, was i d e a l l y suited to control the positioning of the substrate and to control the thick- ness of the deposition at any one point. I t would also be simple to communicate the pattern of phase required to a minicomputer since the pattern would, i n a l l p r o b a b i l i t y , be generated by a large computer. To further investigate the f e a s i b i l i t y of producing phase f i l t e r s by vacuum techniques, additional apparatus had to be designed, constructed and tested. The control strategy had also to be designed and implemented. - 12 - CHAPTER I I - HARDWARE AND SOFTWARE The technique of vacuum d e p o s i t i o n r e q u i r e s a chamber equipped w i t h a pumping system t h a t can maintain pressures lower than 1 x 10 Torr. In t h i s chamber, the source m a t e r i a l to be deposited must be heated to a h i g h tempera- tur e so t h a t i t v a p o r i z e s . The subs t r a t e must be h e l d i n p r o x i m i t y to the source so t h a t the vapour condenses on i t s s u r f a c e . Figure 4 i s a sketch of the vacuum system designed and b u i l t to t e s t the f e a s i b i l i t y of producing a p a t t e r n of v a r y i n g t h i c k n e s s d e p o s i t . The main s e c t i o n of the chamber houses an x-y movement upon which the substrate i s mounted. The x-y movement i s d r i v e n by two stepper motors mounted w i t h i n the chamber and powered from an e l e c t r i c a l feedthrough on the si d e of the chamber. The r e a r of the chamber has a connection to the pumping system. The f r o n t s e c t i o n of the chamber has angled s i d e s and a b a r r e l shaped nosepiece. The s i d e s , which form a "V" w i t h an i n t e r i o r angle of 140 degrees, are f i t t e d w i t h windows such t h a t a l i g h t beam e n t e r i n g the center of one window at r i g h t angles would s t r i k e the substrate at an angle of incidence of 70 degrees and r e f l e c t out the other window. An e l e c t r o m a g n e t i c a l l y operated s h u t t e r i s f i t t e d along the center l i n e of the chamber as c l o s e to the p o i n t of i n t e r s e c t i o n w i t h the r i g h t angles t o the windows as p o s s i b l e without i n t e r f e r i n g w i t h the passage of l i g h t from - 1 3 - HI 1 n rn 1 3 I _ J L O _ 4 - : — i f 1 i A 5 7 8 1 - e l e c t r i c a l feedthrough 2 - vacuum pump connection 3 - x-y motion table and drive motors 4 - o p t i c a l windows 5 - shutter 6 - substrate holder 7 - collimator 8 - source 9 - high current feedthrough Figure 4 . Vacuum Chamber Details - 14 - window to substrate to window. Between the shutter and substrate i s a mask with a square aperture. The b a r r e l of the chamber contains the source. The source i s a round tantalum tube that i s connected to high current e l e c t r i c a l feedthroughs at the end of the b a r r e l . The endpiece also contains an e l e c t r i c a l feedthrough f o r the operation of the shutter. The source shutter and mask a l l l i e along the center l i n e of the chamber. Thus, the source i s only able to deposit material on that section of the substrate v i s i b l e to the source through the mask and then, only when the shutter i s open. The motion of the x-y movement presents d i f f e r e n t areas of the substrate to the source. The windows are f i t t e d i n such a way that the entire chamber can be placed between the two arms of an e l l i p - someter. Thus, the thickness of the area being deposited can be monitored i n s i t u . The chamber i s constructed of helium-arc welded type 316 st a i n l e s s s t e e l . The front section separates from the main chamber to allow s e r v i c i n g of the substrate. The two sections are bolted together and sealed with a large "0" r i n g . The source and feedthroughs are mounted on a flange that i s bolted to the front end of the bar r e l section. The entire chamber i s mounted on a large aluminum plate that f a c i l i t a t e s l o c a t i n g the unit on the ellipsometer. The pumping system connected to the rear of the main chamber consists of a mechanical rotary pump f o r roughing from atmospheric pressures and an o i l d i f f u s i o n pump f o r higher vacuums. This arrangement of pumps i s able to adequately maintain a pressure of less than 1 x 10 Torr. The chamber and x-y movement were designed for this experiment. The construction was carried out by Mr. J. Stuber. The ellipsometer used to monitor film thickness had been previously equipped to make measurements under control of a minicomputer. An ellipsometer i s a device which measures two optical quantities called A and r1 which are related to the reflection coefficients of an optical system by t a n t e J A = ^ £ ( 7 ) Rs where Rp i s the reflection coefficient for parallel polarized light and R i s the reflection coefficient for perpendicular s polarized light. A schematic diagram of the ellipsometer is given in Figure 5. The polarizer and analyzer are polaroids and the quarter wave plate is a Soleil Babinet compensator that introduces a phase change of 90 degrees between the perpendic- ular and parallel polarizations of the light beam. The intensity of the light emerging from the analyzer is given by I = IQ sin2(lP+A) - s i n 2 r s i n 2 ^ - A ' ) (8) A (is defined by - 16 - 1 - laser light source 2 - polarizer with shaft encoder and drive motor 3 - sample 4 - quarter wave plate 5 - analyzer with shaft encoder and drive motor 6 - photomultiplier tube light detector Figure 5.

Making a measurement wi t h the e l l i p s o m e t e r , or balancing the e l l i p s o m e t e r , involves determining a combination of po- l a r i z e r and analyzer s e t t i n g s that produces a n u l l i n the l i g h t i n t e n s i t y emerging from the analyzer. With the quarter wave p l a t e set at -45° to the plane of i n c i d e n c e , at e x t i n c t i o n the r e l a t i o n s between & and P, and V and A are: ^ = 90° - 2P 135° > P > -45° ( 1 0 ) V = A 90° > A > 0 and A = 2P - 90° 225° > P > 45° V = 180°- A 180° > A > 90° A d e t a i l e d l i s t of a l l combinations of analyser and p o l a r i z e r s e t t i n g s that produce a n u l l i s given by F.L. 12 McCrackin et a l . Becaus.e the s i g n a l from the p h o t o m u l t i p l i e r f a l l s to i n s i g n i f i c a n t l e v e l s near a n u l l , i t was not p o s s i b l e to determine the p o s i t i o n of the n u l l d i r e c t l y . F o r t u n a t e l y , both I versus A and I versus P c h a r a c t e r i s t i c s are symmetri- c a l about the n u l l p o i n t . I versus P i s symmetrical provided S i s c l o s e to 90 degrees. Thus, by determining equal i n t e n - s i t i e s on e i t h e r side of the minimum, the p o s i t i o n of the n u l l can be determined as the midpoint. Both the p o l a r i z e r and analyzer are d r i v e n by stepping - 18 - motors geared so that one step rotates the polaroid by 0.01 degrees. The positions of the polarizer and analyzer are measured by a shaft encoder connected to the drive gearing in each unit. The two encoders are read by a multi- plexed decoder to provide a five digit BCD output which ranges from 000.00 degrees to 3'59.99 degrees. The analyzer shaft encoder was mounted in opposition to the scale engraved in the analyzer so that the reading from the encoder must be complimented by 360 degrees to make i t compatible. The light intensity monitored by the photomultiplier i s read through a multiplexed ten bit analog to di g i t a l converter. The ellipsometer had previously been interfaced to a PDP-8e minicomputer. The shaft encoder and photomultiplier were input to the computer and the computer was able to turn the stepper motors on the analyzer and polarizer. The inter- face was expanded so that the computer was able to rotate the stepper motors connected to the x-y drive in the vacuum chamber. The shutter was also operated through the computer interface. Operator communication to the system was made via an ASR-33 teletype. The teletype handler program operates the teletype under interrupt control. A l l input from the key- board is put into a buffer u n t i l i t i s used and removed by a program requiring input. A l l print output i s put into another buffer which the teletype handler tries to keep empty by outputting the contents on the printer. Since teletype input and output are performed on an interrupt basis, the - 19 - computer i s able to carry out control tasks i n the back- ground while serving the teletype. A simple operating system was written to allow an operator to i n i t i a t e control actions from the keyboard. When f i r s t started, the operating system i n i t i a l i z e s f l a g s and counters used throughout the programs i n the system. The only other function of the operating system i s to check the keyboard buffer f o r inputs and translate these inputs into control programs to execute. Commands take the form of two truncated ASCII characters. The operating system compares inputs with a table of names i t recognizes. I f a match i s made, the control program i n the address table corresponding to the name table i s executed. The control programs are a l l subroutines that return to the operating system when they have completed t h e i r task. For t h i s thesis, i t was required to operate the e l l i p s o - meter and the shutter and x-y drive i n the chamber. Also a higher l e v e l program was required to coordinate these controls i n such a way as to produce a deposit of a required thickness. Two commands that were implemented were "set the po l a r i z e r " (SP), and "set the analyzer" (SA). E i t h e r command expected a f i v e d i g i t input from the keyboard that represented the p o s i t i o n required of the analyzer or po l a r i z e r . These two programs f i r s t read the shaft encoder to determine the present p o s i t i o n of the unit and then output the appropriate number of steps to turn the unit to the required p o s i t i o n i n the d i r e c t i o n that required the - 20 - least motion. The two commands to move the x-direction and y-direction stepper motors on the x-y drive in the chamber were given the names MX and MY respectively. The programs associated with these commands expected inputs from keyboard to indicate direction of movement in the plane and the distance of travel. Direction was indicated by "F" and "R". An "F" meant to the right in the x-direction and up in the y-direction when looking at the chamber from the source end. "R" i s the opposite of "F". A l l four stepper motors, the shaft encoder multiplexer and the shutter switch were connected to device 33 in the computer interface. This device was a set of twelve f l i p flops, one per b i t of the computer word as defined in Table 1. The I0P2 pulse from the computer output the accumulator to set the f l i p flops. The I0P4 pulse was used to send a pulse to the stepper motors that had their enable bit set. The pulse was steered to the clockwise or counter- clockwise input on the stepper motor controllers by the direction b it. Thus, any of the four stepper motors could be moved by f i r s t setting i t s enable and direction bits with an I0P2 pulse and then sending an I0.P4 pulse for each step. Once the gating for a motor had been set, a routine labelled STEP was used to output one step pulse to the motor. The motors used had a resonance at approximately 200 steps per second. To run the motors at a speed above the resonance required that they be accelerated from a stopped position. - 21 - Device 3 3 of Computer Interface B i t P o s i t i o n Function 0 P o l a r i z e r motor d i r e c t i o n 1 P o l a r i z e r motor enable 2 Analyzer motor d i r e c t i o n 3 Analyzer motor enable 4 Y-axis motor d i r e c t i o n 5 Y-axis motor enable 6 X-axis motor d i r e c t i o n 7 X-axis motor enable 8 Unused 9 Unused 10 Shutter control 11 Shaft encoder gate Table 1 - 22 - Since timing was generated by software, i t was not convenient to run more than one motor at a time. The hardware status of device 33 was stored in a location labelled DIR. Bit 9 of DIR was used for a flag to indicate that acceleration was required. The routine STEP accelerated the motors by shorten- ing the time between pulses from a maximum when the flag was f i r s t set to a minimum after a certain number of pulses had been sent. At this time the flag was cleared. The output of the multiplexed shaft encoder was connected to device 30 in the interface. The shaft encoder was always set to read the analyzer when the analyzer motor was selected, and the polarizer, when the polarizer motor was selected. The I0P2 pulse was used to strobe the high order two BCD digits into the accumulator and the I0P4 pulse was used to strobe the three low order BCD digits. These numbers were read by a program named RDSFT and were stored in locations SHFTH and SHFTL respectively. The output from the photomultiplier on the ellipsometer was measured by the computer with an analog to d i g i t a l converter, device 32 in the interface. The program, ANALG, was responsible for reading the analog to d i g i t a l converter and converting the reading into volts. To take a reading from the ellipsometer requires that the polarizer and analyzer be positioned so that the output from the photomultiplier i s a minimum. The suggested procedure i s to f i r s t balance, that i s , find a minimum of, 11 the polarizer. Then the analyzer i s balanced. The - 23 - polarizer i s again balanced and f i n a l l y the analyzer i s balanced again. This procedure can be commanded from the keyboard with a BE input. The procedure i s really a combina- tion of the two commands BA and BP which balance the analyzer and polarizer respectively. These two routines set the gating for the appropriate stepper motors and then c a l l upon a common routine called BALU. The routine BAL (see Figure 6) determines the position of a minimum photomultiplier reading by finding equal intensities around a minimum. To avoid noise problems due to low signal levels, the sum of many readings is taken. Fi r s t a running sum of readings is taken by moving the motor one step, reading the photomultiplier and adding the reading to the sum. The sum is taken over sixty-four steps. A second running sum i s taken and compared with the f i r s t . If the second sum i s larger, the motor i s reversed and the routine restarted. Otherwise, the f i r s t sum i s replaced by the second and the second sum is taken again and again compared with the f i r s t . A flag i s set to indicate the minimum has not yet been passed. At some point the second sum w i l l be larger than the f i r s t indicating that the minimum has been passed. Another set of readings i s taken and this sum is saved as the comparison on one side of the minimum. The motor i s reversed and run back two sets of readings. The next set of readings is saved, reading by reading, along with the running sum. From here on, every time the motor is stepped, the newest reading is put at the beginning of the - 24 - FLOWCHART OF SUBROUTINE BAL BAL J ENTRY POINT, 1-+BLFLAG SET FLAG TO INDICATE MINIMUM' NOT BEING APPROACHED.

The running sum is also adjusted by adding on the newest reading and subtract- ing the oldest. This running sum i s compared with the comparison sum and as soon as i t is equal to or larger than the comparison sum, the position of the minimum can be determined as the midpoint of the two sums. The motor is reversed and driven to the midpoint. The analyzer and polarizer positions and photomultiplier reading at the bal- ance point are printed on the teletype. The shutter in the chamber could be operated from the keyboard with the two commands "open shutter" (OS), and "close shutter" (CS). These commands changed the state of a f l i p flop on device 33 in the interface. The shutter s o l e n o i d was energized by a power transistor driven by the f l i p flop. Closed loop control of film thickness was accomplished by setting the analyzer and polarizer to the positions at which a balance would occur i f the film were the correct thickness. The shutter was then opened un t i l the photo- multiplier output dropped to a minimum. The shutter was closed to stop the deposition process. This procedure was commandable from the keyboard and given the name SB, "stop on balance". For noise immunity, the SB program uses sums of readings instead of a single reading of the photo- multiplier. A typical sequence of commands that produces a deposit of a specified thickness is the following: - 3 1 - MX F 0 0 1 MY F 0 0 1 SA 4 7 . 2 1 SP 3 2 5 . 5 4 SB The MX and MY commands move the substrate to a desired p o s i t i o n and the SA and SP commands move the analyzer and p o l a r i z e r to the balance p o s i t i o n . The SB command f i n a l l y opens the shutter and closes i t when a balance occurs. The distances f o r the MX and MY commands are i n units of the mask aperture width so that adjoining areas can be reached by moving i n increments of one. The teletype input program was written so that the paper tape reader on the ASR 3 3 was enabled i f there was room i n the input buffer. Thus, the operation of the system could be controlled with commands stored on paper tape. In t h i s way the thickness pattern of the substrate could be generated on a large computer system where i t could be converted to analyzer and p o l a r i z e r settings. The large computer system would then generate an ASCII paper control tape. The physical pattern could then be produced with the hardware described by read- ing t h i s tape. - 3 2 - CHAPTER III - RESULTS AND CONCLUSIONS To test the performance of the equipment, two experi- ments were conducted. The f i r s t experiment consisted of depositing material to study the deposition process and products. The second experiment was a check of the closed loop control of the system. The substrate used was an optical glass f l a t , 25 x 2 5 millimeters. The substrate was coated with a layer of vacuum deposited aluminum to give i t a reflecting surface. The substrate was transferred to the x-y movable holder in the vacuum chamber. The chamber was evacuated in prepara- tion for deposition of zinc sulfide. Before any depositions were made on the bare aluminum surface of the substrate, the surface was checked for uniformity. This was accomplished by moving the x-y holder so that the ellipsometer could take readings of different areas of the surface. A map of the surface uniformity is given in Table 2 . The x-y holder was then set to a corner of the substrate and the evaporation current turned on. The shutter was opened and zinc sulfide allowed to deposit through the aperture onto the substrate. The ellipsometer was used to observe the evaporation process. After a suitable thickness of zinc sulfide had been deposited, the evaporation was halted by closing the shutter. The x-y holder was then moved a distance equal to the width of the aperture, - 33 - • • • 56.85 ' 56.69 56.50 « 55.76 !

Scan of Aluminum Coated Substrate - 34 - 1.59 millimeters. The shutter was then again opened to deposit onto an area adjacent to the f i r s t . A thickness of zinc s u l f i d e d i f f e r e n t from the f i r s t area was then deposited on the second. The procedure was repeated f o r a t h i r d time to form three adjacent areas of d i f f e r e n t thicknesses. After the t h i r d area, the shutter was closed and the x-y holder moved at r i g h t angles a' distance twice the width of the aperture. At t h i s position, a thickness of zinc s u l f i d e was again deposited. The holder was then positioned a l i t t l e beyond the edge of the l a s t square deposited and an ellipsometer reading was taken. The holder was then moved a small distance, 47 micrometers, towards the square and another reading was taken. This process was repeated u n t i l the p r o f i l e of the entire square was obtained. The holder was then positioned near the area of the three adjacent squares and a s i m i l a r scan was made along the center l i n e of the three squares. The readings are presented graphically i n Figures 7, 8 and 9. The second experiment was performed to determine the c a p a b i l i t i e s of the control system. For t h i s experiment d i f f e r e n t areas of the same substrate were used. Suitable values of p o l a r i z e r and analyzer readings were chosen from the f i r s t set of evaporations. These readings were used to produce a control tape f o r the second experiment. Four areas adjacent to one another were to be evaporated upon. The vacuum system was prepared and evacuated.

The photomultiplier reading was observed while the process was taking place. The control system successfully found a null on the f i r s t square deposited, halted deposition and went on to the next square. On the second square, the null was very shallow and two shallow nulls were bypassed before manual intervention caused the process to proceed to the third and fourth squares. The control system again successfully detected nulls on these two areas and halted evaporation. After the fourth square, the evaporation current was turned off and the ellipsometer was used to scan the center line of the four squares taking readings at short intervals. The scan is graphically presented in Figures 10 and 11. Finally, the holder was moved to a bare area and with the shutter open, continuous ellipsometer readings were taken. The A-f curve from this data was plotted in Figure 12. Using the average values of polarizer and analyzer readings from Table 2, the optical constants of the aluminum substrate, as viewed through the windows on the chamber, 11 were determined using McCracken's program. Using values for the index of zinc sulfide, the A~f curve for the f i l t e r was calculated again using McCracken's program. This curve i s presented graphically in Figure 13. The scan of the bare aluminum substrate indicated that Analyzer Figure 1 0 . Analyzer Scan f o r Squares Deposited While on Control F i g u r e 1 1 .

The •A and V readings f o r the aluminum covered s u b s t r a t e , however, do not f i t on the c a l c u l a t e d curve f o r z i n c s u l f i d e on aluminum. The reason f o r t h i s i s probably t h a t the "bare" aluminum i s not r e a l l y bare but has a c o a t i n g of aluminum oxide which forms when aluminum i s exposed to a i r . T h e r e f o r e , the e l l i p s o m e t e r i s a c t u a l l y measuring the aluminum and aluminum oxide l a y e r as the s u b s t r a t e . The r e s u l t s of the f i r s t experiment i n d i c a t e mixed con- c l u s i o n s . The e l l i p s o m e t e r scan of the d e p o s i t e d squares p o i n t to nonuniform d e p o s i t i o n s and t h i s was confirmed by v i s u a l examination of the s u b s t r a t e . The squares l a b e l l e d 2 and 4 i n F i g u r e s 7, 8 and 9 were uneven. The scan does, however, show c l e a r l y the d e f i n i t i o n of the squares. The edges of the square are d e f i n e d by d r a s t i c changes i n e l l i p s o m e t e r readings and the c e n t e r s e c t i o n s are reasonably smooth. The e l l i p s o m e t e r curve drawn from the measurements of the second experiment, F i g u r e 12, d i f f e r s from the t h e o r e t i c a l curve f o r z i n c s u l f i d e on aluminum, F i g u r e 13. Again, the most probable cause f o r t h i s i s the c o a t i n g of aluminum oxide on the bare s u b s t r a t e . The index of vacuum dep o s i t e d z i n c s u l f i d e f i l m s has been d i s c o v e r e d to depend on the d e t a i l s of d e p o s i t i o n such as r a t e of d e p o s i t i o n , 8 temperature and p r e s s u r e .

The shutter was automatically closed to stop deposition a f t e r just passing the low point of a minimum from the ellipsometer readings. A poor sel e c t i o n process caused values of p o l a r i z e r and analyzer readings to be chosen as setpoints. The chosen readings did not f a l l ' o n the curve of Figure 12. The poor set- points were evidenced by the shallow minimum i n the ellipsometer output. The control system stopped deposition when i t came as close as possible to the setpoints. During the deposition of the square l a b e l l e d "D" i n Figures 10 and 11, a sharp minimum was observed and as seen from l a t e r analysis, the control system came very close to the desired setpoints. The setpoints are shown as dotted straight l i n e s i n Figures 10 and 11. The equipment b u i l t and experiments made have only tested the f e a s i b i l i t y of producing phase f i l t e r s with vacuum deposition techniques. To produce useful devices, the s p a t i a l resolution of the deposition system must be increased by an order of magnitude. This involves smaller apertures and closer tolerances on the positioning mecha- nisms. The experiments conducted have shown that the resolution used i s attainable. The deposition system must be c a l i b r a t e d and errors introduced by the surface condition of the substrate must be accounted f o r . During the tests of t h i s thesis, these factors were ignored as only r e l a t i v e - 45 - thickness of deposit was aimed f o r . The control and measurement systems seem capable of the tasks required of them. Thus, i f further tests to c a l i b r a t e the system were made, absolute thickness variations should be achievable. In summary, a method of f a b r i c a t i n g o p t i c a l phase f i l t e r s has been investigated. Possible uses of an o p t i c a l phase f i l t e r have been proposed. The hardware to f a b r i c a t e such a phase f i l t e r using vacuum deposition techniques was designed and constructed. Software was written to control production of the phase f i l t e r s by a d i g i t a l computer. And f i n a l l y , the f i r s t steps were taken to produce the devices. The d i f f i c u l t i e s encountered were not fundamental i n nature and require only refinements i n technique to solve. - 46 - REFERENCES AND BIBLIOGRAPHY 1.
