Remote distribution of a mode-locked pulse train with ultralow jitter Chen, Yi-Fei

Abstract

Remote transfer of an ultralow-jitter microwave frequency reference signal is demonstrated using the pulse trains generated by the mode-locked fiber laser. The timing jitter in a 30 - m fiber link is reduced to sub-40 attoseconds (as) integrated over a bandwidth from 1 Hz to 10 MHz via active stabilization which represents significant improvement over previously reported jitter performance. results. An all-optical generation of the synchronization error signal and an accompanying out-of-loop optical detection technique are applied to verify the jitter performance.
