| Abstract(in English) | We propose an optoelectronic 1:4 demultiplexing circuit applicable to 160 Gsymbol/s systems. Our demultiplexer is based on a tree-type configuration of dual-port Mach-Zender modulators (MZMs), which achieve optoelectronic functions of 1:2 serial-to-parallel conversion and clock recovery. Since our proposed scheme only requires a quarter bandwidth of the optical symbol rate frequency, we can perform demultiplexing of 160 Gsymbol/s signals using 40 GHz electronics. With our scheme, we conduct experiments of demultiplexing and clock recovery of 160 Gbit/s RZ-OOK optical signals, where bit error rates of all tributaries better than 10^<-9> are achieved for the input signal power over -23 dBm. After 160 Gbit/s RZ-OOK signals are transmitted through a 40-km dispersion shifted fiber, our demultiplexer can achieve receiver sensitivities better than -23 dBm for all tributaries. |
