Abstract :
Cross-phase modulation (XPM) and cross-gain modulation (XGM) in a semiconductor optical amplifier (SOA) pumped by assist light were experimentally analyzed. A simple analysis technique for evaluating the XPM separately from the XGM was proposed utilizing a polarization-discriminating delayed interferometer. An initial phase deviation and a gain recovery time in SOA with injecting assist light were quantitatively estimated.
