摘　　要：阐述了半导体光放大器(SOA)的分段模型理论;列举了三种SOA分段模型,并分别用这几种模型对基于交叉增益调制效应的光波长转换进行了仿真计算。通过比较和分析不同模型的仿真结果与实验现象的差异,说明在基于SOA的全光信号处理过程中,有源区内的放大自发辐射(ASE)对光信号的增益压缩与光脉冲的形态具有不可忽视的作用。The theory of multi-section model for semiconductor optical amplifier （SOA） is described. Three multi-section models are presented and applied to the simulation of wavelength conversion based on cross-gain-modulation in SOA. By analyzing the difference between the simulated and experimental results, it is emphasized that the amplified spontaneous emission （ASE） has important effects on the gain compression and pulse-shaping during the all-optical signal processing based on SOAs.
