Fsor the potential applications in WDM optical networks, the wavelength conversion process is analyzed in time domain using the cross phase modulation (XPM) in the SOA-MZI structure. When the power of Gaussian input pulse are 1mW, 2mW and 4mW, the extinction ratio of the output converted pulse are 20dB, 23dB and 26dB, respectively. The output pulse maintains the extinction ratio over 10dB independent of the extinction ratio of input pulse for the conversion bandwidth of 15nm. The maximum pulse width increase ratio of 1.6 was obtained for 15nm wavelength conversion.
