摘 要: | 提出了一种基于单端半导体光放大器(SOA)的交叉增益调制型(XGM)全光波长转换器结构, 并针对这种结构建立了动态理论模型, 以这个模型为基础分析了泵浦光功率、探测光功率、输出消光比、输入消光比对转换后信号啁啾的影响. 结果表明利用这种结构的波长转换器实现波长转换, 在提高输出消光比的同时也降低了转换光的啁啾, 较传统的波长转换器是一种改进.

Abstract: | A new all optical wavelength converter (AOWC) using single port coupled semiconductor optical amplifier (SOA) based on cross gain modulation (XGM) was brought forward, and a dynamic model was presented. Based on the dynamic model, factors which affect converted signal chirp, such as signal power, probe power, output extinction ratio, input extinction ratio, were analyzed respectively. The numerical result shows that converted signal chirp decreases in some extent when using this kind of wavelength converter. |
