摘要
仿真并分析了基于半导体光放大器全光偏振调制的双信道光传输系统模型.该系统分别利用两级半导体光放大器的交叉偏振调制效应(XPolM),将两路独立的强度调制的抽运光变换到一路探测光的两个正交的偏振态上,实现双通道偏振复用的全光数据传输.首先对单个半导体光放大器的动力学过程进行了理论分析,数值计算了具有不同抽运光功率的半导体光放大器对探测光偏振态的影响,进而对双半导体光放大器偏振复用系统的调制/解调原理进行了分析,模拟仿真了双半导体光放大器的双通路偏振复用的调制及解调过程,仿真结果与实验结果相符.
Abstract
A theoretical model of a dual-channel polarization optical transmission system is analyzed,using two semiconductor optical amplifiers (SOAs) to achieve all-optical polarization modulations with two input data streams.In this model,the signal polarization modulation is completed by utilizing the cross polarization modulation (XPolM) effect in the SOA.A rate equation of the tensile-strained bulk SOA is adopted in the model.With this model,the dynamic characteristics of the system in respects of the amplification and the phase difference of the probe light in SOAs,signal polarization multiplexing and demultiplexing are investigated numerically.The simulated and experimental results are well consistent.
