摘要 文章设计了一种快速实用的自适应偏振模色散(PMD)补偿器,主要利用x切、y向传播的L iNbO3器件的双折射特性进行了光纤链路PMD的补偿,采用一定频率范围内的功率谱密度作为补偿器的反馈控制信号,并使用了多维梯度搜索算法优化补偿量。 We present the design of an adaptive polarization mode dispersion compensator, it is fast and applied. The birefringent characteristic of x cut, y propagation LiNbO3 is used to compensate fiber PMD, power spectrum density works as feedback control signal, and multi-dimensional gradient searching algorithm optimize the value of compensation.
