摘　　要：量子点半导体光放大器具有比传统半导体光放大器更快的载流子恢复时间,基于QD-SOA交叉增益调制的波长转换技术具有转换速率快,无pattern effects效应的特点。对有源区长度,输入信号光功率和转化后信号的消光比和脉冲展宽进行了研究,对提高基于QD-SOA交叉增益调制波长转换的性能具有指导意义。The carrier recovery time in quantum dots semiconductor optical amplifier （QD-SOA） is shorter than that in the conventional semiconductor optical amplifier. The wavelength conversion based on QD-SOA＇s cross gain modulation （XGM） can adapt on higher conversion rate and conquer the pattern effects. The rela- tionships between extinction ratios, converted pulse width and the length of active region, input signal power has been studied in this paper. The results will benefits the realization and performance improvements of wavelength conversion based on QD-SOA＇s XGM effects.
