Abstract

We develop a complete large-signal dynamic model of semiconductor optical amplifier (SOA)based wavelength converters using cross-gain modulation (XGM) and cross-phase modulation (XPM). The large-signal dynamic model has been implemented using the modified transfer matrix method (TMM). This model takes account of longitudinal variations of carrier-induced refractive index, α-parameter, internal reflection, photon density, and amplified spontaneous emission (ASE) noise at each small section. Therefore, we can accurately estimate frequency chirping, optical pulse patterns, and extinction ratio of the wavelength-converted signal in SOAs. Frequency chirping and extinction ratio have been calculated for various parameters such as signal and CW power, and facet reflectivity.
