Analysis of Extinction Ratio Characteristics in All-Optical Wavelength Conversion Based on Cross-Gain Modulation
A theoretical model of wavelength conversion based on cross gain modulation in a semiconductor optical amplifier (SOA) has been established. The influences of SOA bias current as well as pump and probe light parameters on extinction ratio characteristics of converted signals are discussed. The results show that higher pump power, lower probe power and suitable wavelength spans between pump and probe light wavelengths have the advantages to achieve the higher extinction ratio.
