Using this model, the saturation property and dynamic performance of the quantum dot semiconductor optical amplifier are analyzed by PSPICE simulation. We also investigate wavelength conversion based on cross-gain modulation for the quantum dot semiconductor optical amplifier. The corresponding results are in agreement with the previous published works.
