Cross-talk analysis of optical time-division demultiplexer

We have developed a simulation model to investigate the demultiplexing of a ll-optical-time-division-multiplexed data, employing an optical time-divisi on demultiplexer. Particular attention is paid to the cross-talk performanc e when selected parameters of the system are varied. The system used to dem ultiplex the data is the asymmetric semiconductor laser amplifier loop mirr or (ASLALOM), which is capable of selecting high-speed optical pulses withi n a data train. The authors use a model of the ASLALOM that includes a time and space analysis of a traveling-wave semiconductor laser amplifier. Our investigation shows that this system produces cross talk that is dependent on the data rate, control pulse energy, and control pulse rate.
