摘　　要：从速率方程出发 ,采用分段模型对半导体光放大器 (SOA)的皮秒增益和折射率非线性进行了数值模拟 ,具体分析了注入光脉冲引起的载流子浓度的变化、输出光脉冲时域波形的畸变、注入光脉冲引起的增益和位相变化 ,以及输出光脉冲上的频率啁啾。Pico-second gain and refractive index nonlinearities in semiconductor optical amplifiers (SOAs) were simulated using a multi-section model from the start of the rate equation. Carrier density variation induced by pulse injection, aberration of the temporal profile of the output pulse, gain and phase change induced by pulse injection, and frequency chirp on the output pulse were analyzed.
