Research on the algorithm of complete polarization scrambling of polarization controller

从一种偏振度测试系统的系统结构出发建立光路传输模型,在分析光纤挤压型偏振控制器的工作原理后,给出整个光路传输模型的穆勒矩阵。在此基础上,文中重点研究了偏振控制器的完全扰偏算法,并用MatLab对算法进行了仿真。仿真结果表明该算法能够实现完全扰偏并有效提高偏振度测试精度。

The paper begins with establishing a optical transmission model from a structure of degree of polarization （DoP） measuring system, after analysing the working principle of the fiber squeezer polarization controller, it figures out the Mueller matrix of the entire optical transmission model. Based on the above, the paper puts the emphasis on the algorithm of complete polarization scrambling of polarization controller, and employs the MatLab to have a simulation. The results of simulation show that the algorithm can achieve the goal of complete polarization scrambling and improve the measuring precision of the DoP efficiently.
