| 摘 要： | 作为自动交换光网络中的核心器件,全光波长转换器将在全光通信系统中发挥重要作用.根据半导体激光器实现波长转换的理论模型,重点研究了基于DFB实现波长转换器的误码特性.包括工作电流、输入信号光功率等参量对消光比、误码率的影响.并利用自行搭建的基于DFB实现波长转换的实验平台,进行了实验分析,发现理论分析结果和实验数据十分吻合.这对于优化基于DFB结构的全光波长转换器有重要参考价值.

| Abstract: | The bit error rate(BER) of wavelength conversion using distributed feedback(DFB) is discussed based on the theory model of all optical wavelength conversion realized by semiconductor lasers.The characteristics such as extinction ratio and BER of wavelength conversion are analyzed in different optical parameters including the injection current,the signal average power.Experimental results are studied synchronously using a set of experimental equipment of DFB semiconductor laser for all optical wavelength con... |
