摘　　要：对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建立了动态理论模型,以这个模型为基础分析了抽运光功率、探测光功率、剩余反射率、转换波长转换间隔、注入电流对转换后探测光的输出消光比的影响。结果表明,利用单端SOA实现波长转换比普通SOA实现波长转换将获得更好的输出消光比特性。The dynamic model for a new all-optical wavelength converter (AOWC) using single-port-coupled semiconductor optical amplifier (SOA) based on cross gain modulation (XGM) is presented.Based on the dynamic model,factors which affect output extinction ratio,such as signal power,probe power,rear facet reflectivity,converted wavelength span,biased current,are analyzed respectively.The numerical result shows such a converter do have better extinction ratio character than a traditional AOWC.
