By utilizing the cross polarization modulation effect in semiconductor optical amplifier (SOA), the extinction ratio of cross gain modulation (XGM) wavelength conversion was enhanced, the pattern effect was significantly reduced, and the power penalty of wavelength conversion was reduced by 5 dB simultaneously. Furthermore, by adjusting the settings of polarization controllers, both inverted and non-inverted wavelength conversion can be achieved right in the same wavelength converter.
