Paper Abstract

A steady state numerical model of wavelength conversion through cross-gain modulation in semiconductor optical amplifiers is developed. Increased understanding and accuracy over previous studies are achieved by including the spatial variations and wavelength dependence of the carrier density, gain coefficient, differential gain, and waveguide internal loss. The model is used to evaluate the performance of up-converters and down-converters for long and short device lengths. A comparison is made between the model developed in this work with other theoretical and experimental studies.
