摘　　要：本文详细分析了饱和工作状态下的行波半导体光放大器（ＴＷ－ＳＯＡ）的啁啾特性，从理论上证实了利用其增益饱和所引起的自相位调制来对光源啁啾进行相位补偿的可行性，并且发现，对于不同脉宽的入射脉冲，光放大器均能发挥相位补偿的作用，这一特性可用来补偿光源啁啾．Abstract The chirp characteristics of traveling-wave semiconductor optical amplifiers (TW-SOAs) are analyzed in detail. The phase compensation of light source chirp using self-phase modulation (SPM) induced by gain saturation in a TW-SOA was theoretically demonstrated. The possibility of phase compensation is shown in all the cases of different input pulse widths much shorter, comparable, and far longer than the amplifier carrier lifetime. This feature can be used to compensate light source chirp.
