Abstract :
40 Gbit/s reconfigurable photonic logic gates with XNOR, AND, NOR, OR and NOT functions are demonstrated, based on various nonlinearities of a single semiconductor optical amplifier (SOA), including four-wave mixing (FWM), cross-gain modulation (XGM) and transient cross-phase modulation (T-XPM). Detuning optical bandpass filters are employed to enhance the SOA modulation bandwidth.
