Abstract :
Summary form only given. We have experimentally demonstrated wavelength conversion using polarization dependence of photo-induced phase shift in a compressive-strained InGaAsP MQW-EA modulator. It requires relatively small signal power less than +8 dBm (coupling loss is included). It also gives high extinction ratio more than 25 dB as well as enlargement of extinction ratio from 10 dB (signal light) to 23 dB (wavelength-converted light).
