Abstract A theoretical model including gain compression and gain ripples to calculate the wavelength conversion efficiency is established based on four wave mixing(FWM) in a semiconductor optical amplifier(SOA) in this paper. The influence of gain differences among the pump, signal and converted light wavelengths, and gain compression on the conversion efficiency are discussed. The results show that the pump light positioned at the gain peak and the lower gain compression ratio have the advantage for increasing the wavelength conversion efficiency.
