Abstract

Frequency chirp characteristics of wavelength converters based on cross-gain modulation (XGM) in a semiconductor optical amplifier (SOA) is analyzed with a theory analytical model. The numerical simulation results show that the input pump power and probe power, the probe wavelength and the pump wavelength have direct influence on the chirp characteristics. We found that the output pulse of the converted light undergoes a blue shift during the rising edge and a red shift during the falling edge. In order to reduce the frequency chirping, high probe power, low pump power, and appropriate wavelength region of the signal and the probe are favorable.
