All-optical clock-division operation using a mode-locked fiber laser based on the slow carrier recovery rate of SOA

Summary form only given. In OTDM systems, separate channels at the same frame rate are multiplexed in time domain into a high-speed aggregate data stream. To access the individual time slots, high-speed all-optical clock division can be used to generate optical clock signal at the frame rate for time-domain demultiplexing. We build a numerical model of a mode-locked semiconductor fiber laser that uses a TOAD as an optical modulator and performs clock division. Moreover, we show that clock division operation can be realized when the SOA in the TOAD has a relatively slow carrier recovery rate
