Abstract :
A wideband steady-state model of a MQW-SOA is described. Least-squares fitting of the model to experimental polarization resolved amplified spontaneous spectra were used to obtain difficult to measure model parameters such as the intraband broadening energy, Auger recombination coefficient and the bandgap shrinkage coefficient. Simulations and comparisons with experiment are given which demonstrate the accuracy and versatility of the model.
