Nonlinear State–Space Model of Semiconductor Optical Amplifiers With Gain Compression for System Design and Analysis


In this paper, we derive a new analytical state-space model for semiconductor optical amplifier (SOA) dynamics with nonlinear gain compression. We show that a multichannel closed-form state-space model is possible with polynomial gain compression and position-independent carrier density. The compressed model is significantly more accurate than existing… (More)
