摘要：
In order to improve the wavelength conversion efficiency of all-optical wavelength converter, the conversion efficiency of all-optical wavelength converter based on the cross-gain modulation (XGM) effect and the cross-phase modulation (XPM) effect is analyzed on the basis of the research of wavelength conversion characteristics of quantum dot semiconductor optical amplifier (QD-SOA). Based on the XGM type all-optical wavelength converter and the three-level QD-SOA model, the effects of input pulse width, active region length, loss coefficient, maximum gain mode and electron transition time on conversion efficiency are calculated. The results show that reducing the input pulse width, loss coefficient and electron transition time and increasing the active region length and the maximum gain mode can improve the conversion efficiency of all-optical wavelength converter. The study is useful for the design of all-optical logic XOR gate and the application of QD-SOA. © 2017, Chinese Lasers Press. All right reserved.
