A phase stabilized quadruple OTDM multiplier for RZ/CS-RZ optical clock with a flat-top optical bandpass filter

摘要

Our work focuses on the study of a phase stabilized quadruple RZ/CS-RZ optical clock multiplier. This quadruple OTDM multiplier is composed of two Mach-Zehnder interferometers. In this presentation, we propose to use a flat top OBPF to filter three desired sidebands from the OTDM multiplexed output. The filtered output is used for the stabilization. Further simulations were done to characterize the influence of OBPF shape on stabilization.
