摘　　要：本文分析了半导体激光放大器处于增益饱和状态下的自相位调制（SPM）效应,以及SPM效应对传输脉冲波形、相位及频谱的影响。指出了利用这种效应可以补偿传输光纤色散。但是,必须仔细选择传输系统的配置和放大器结构参数,以获得最佳色散补偿效果。In this pager, the self-phase modulation effect in gain saturated semiconductor optical amplifier and its affect on the shape, phase and spectrum of transmission pulse are analyzed. We also point out that the dispersion of transmission fiber can be compensated for with this effect. But in order to acquire an optimum dispersion compensation, the disposal of system and the structure parameters of amplifier must be chosen carefully.
