摘 要：Our work focuses on the study of a phase stabilized quadruple RZ/CS-RZ optical clock multiplier. We used a flat-top OBPF to filter 3 consecutive sidebands from the OTDM multiplexed output. The filtered output is used for the stabilization. In this presentation, we made a simulation to obtain the tolerance of center frequency offset of the filter versus its bandwidth and shape factor in order to find out the required OBPF parameters for the optical clock multiplier.
