为了改善全光波长转换器的转换性能进而提高波长转换效率，在量子点半导体光放大器（QD-SOA）波长转换特性研究的基础上，分别对基于交叉增益调制（XGM）和交叉相位调制（XPM）两种效应的全光波长转换器的转换效率进行了仿真分析。利用三能级量子点半导体光放大器模型基于 XGM 型全光波长转换器，计算了输入脉冲宽度、有源区长度、损耗系数、最大增益模式、电子跃迁时间变化时的转换效率；基于 XPM型全光波长转换器，计算了最大增益模式、损耗系数、电子跃迁时间变化时的转换效率。结果表明，减小输入脉冲宽度、损耗系数、电子跃迁时间，增加有源区长度、最大增益模式均可以提高波长转换器转换效率。研究结果对全光逻辑异或门的设计及 QD-SOA 的应用有一定的指导意义。
In order to improve the conversion performance of the all-optical wavelength converter and further improve the wavelength conversion efficiency, based on the research of the wavelength conversion characteristics of the QD-SOA, the effects of cross-gain modulation (XGM) and cross-phase modulation ) Conversion efficiency of all-optical wavelength converter with two kinds of effects was simulated and analyzed. Based on the XGM all-optical wavelength converter, the conversion efficiency of the input pulse width, active region length, loss coefficient, maximum gain mode and the change of electron transition time were calculated by using the three-level quantum dot semiconductor optical amplifier model. Optical wavelength converter, calculated the maximum gain mode, loss factor, the electronic transition time when the conversion efficiency. The results show that the efficiency of the wavelength converter can be improved by reducing the input pulse width, the loss coefficient, the electronic transition time, the increase of the active region length and the maximum gain mode. The results of this study are of guiding significance to the design of all-optical logic XOR gate and the application of QD-SOA.
