| Abstract: | The output noise characteristics of the wavelength conversion due to the cross gain modulation (XGM) in a semiconductor optical amplifier (SOA) are studied theoretically. An analytic expression to describe the influences of input optical parameters on noise characteristics of converted signals is developed. The numerical simulation results show that higher pump power, lower probe power, as well as suitable wavelength conversion spans are the advantages to the improvement of the noise characteristics. |
