Noise transfer characteristics of wavelength converters based on cross gain modulation (XGM) in semiconductor optical amplifiers (SOAs) is analyzed with a small signal model. The numerical simulation results show that the input pump power and probe power and the gain of SOA have direct influence on the noise transfer. In an appropriate range of input power, the noise can be effectively suppressed, and quality of converted signal is improved.
