摘　　要：对半导体光放大器 (SOA)中光偏振态发生改变的原因和交叉偏振调制型波长转换进行了探讨和分析 .如果SOA具有偏振不灵敏增益 ,则波长转换效果与泵浦光的偏振态无关 ,而只与探测光的偏振态有关 ,而且当入射探测光的偏振与TE模振动方向成 4 5°夹角时 ,交叉偏振调制的效果最明显 .为了使转换效果更好 ,宜采用反相波长转换 ,SOA的自发辐射耦合因子Polarization change in a semiconductor optical amplifier (SOA) is analyzed.For wavelength conversion based on cross polarization modulation,it is demonstrated that if SOA has polarization independent gain,the polarization of pump wave has no effect on wavelength conversion but the polarization of input probe wave does,and the extinction ratio is maximum when input polarization angle is 45°.It is also shown that inverted conversion is superior to noninverted conversion,and that a more significant conversion effect will be achieved if the coupled spontaneous emission factor β is smaller.
