摘要

行波半导体激光放大器(TWA)[1]-[4]可以极大地简化波分复用(WDM)系统中使用的光中继器，因为其宽增益带宽允许单个TWA同时放大不同波长的信号。尽管这种系统在线性增益范围内的性能仅由放大器噪声特性决定[5]，[6]，但光放大器中非线性效应的发生会导致串扰[7]。

Nonlinear Effects in Semiconductor Optical Amplifiers

A traveling-wave semiconductor laser amplifier (TWA) [1]-[4] can greatly simplify optical repeaters used in wavelength-division-multiplexed (WDM) systems, since its wide gain band width allows a single TWA to simultaneously amplify signals of different wavelengths. Even though such system performance in the linear gain regime is determined only by amplifier noise properties [5],[6], the onset of nonlinear effects in optical amplifiers result in crosstalk [7].
