Abstract :
Nonlinear distortions induced by four-wave mixing and gain saturation in a semiconductor laser amplifier can affect the overall performance of lightwave systems using such devices. A model which includes both types of distortion in a three-channel optical transmission system is presented. Large-signal analysis is used to calculate distortion in amplifiers operating near saturation. The technique provides more realistic predictions than the small-signal rate equation analysis used in previous theoretical studies of four-wave mixing in optical amplifiers.<>
