Abstract

Semiconductor optical amplifiers (SOAs) are very attractive components for optical communication systems. We have already shown that two-cascaded SOAs in a counterpropagating configuration (TC-SOA-CC) based on XGM is interesting for all-optical signal processing (Kim et al., 2000). The contra-directional input signals are injected in SOA. In this configuration, a negative feedback controls the evolution of the SOA gains. The presence of a positive gain variation in SOA can be useful to perform all-optical logic OR gate at the output of SOA.
