Spectral response tuning of photoconductive terahertz emitters with binary phase masks Dekock-Kruger, Shaylene; Collier, Christopher Michael; Stirling, Trevor J.; Holzman, Jonathan F.
Abstract
In this work, binary phase masks are designed and implemented for use with a photoconductive terahertz (THz) emitter in order to shape the frequency response of the emitted THz waveforms. Theoretical and experimental results are applied to study the system. The theoretical results are presented in the form of both numerical simulations (to characterize and uniquely identify the underlying time-delayed photogeneration and resulting charge-carrier dynamics) and a simplified model (to conceptualize the system). The theoretical and experimental results are found to agree. It is ultimately shown that the phase delay through the binary phase mask can be used to preferentially allocate power into bands within the THz spectrum. Such results can lay the groundwork for future studies needing precise control of power within the THz spectrum.

In this work, binary phase masks are designed and
implemented for use with a photoconductive terahertz (THz)
emitter in order to shape the frequency response of the emitted
THz waveforms. Theoretical and experimental results are applied
to study the system. The theoretical results are presented in the
form of both numerical simulations (to characterize and uniquely
identify the underlying time-delayed photogeneration and
resulting charge-carrier dynamics) and a simplified model (to
conceptualize the system). The theoretical and experimental
results are found to agree. It is ultimately shown that the phase
delay through the binary phase mask can be used to preferentially
allocate power into bands within the THz spectrum. Such results
can lay the groundwork for future studies needing precise control
of power within the THz spectrum.
