摘要
利用琼斯矩阵分析了适合高速应用的四通道挤压光纤型偏振控制器的复位原理,根据复位原理设计了以两通道为主延迟器,另两通道为辅助复位延迟器的复位方案,并以40Gb/s的PMD补偿系统为实验平台进行了验证,反馈信号及四通道控制电压和时间的关系曲线表明复位效果良好且复位未对PMD补偿产生不良影响。
The reset principle of dynamic polarization controller is analyzed by using the Jones＇ Matrix, which is based on four optical fiber squeezers and suitable for high speed optical communication system. The reset scheme is presented. The verifying experiment is taken in 40 Gbit/s PMD compensation system, the performance is good and the endless polarization control has no unfavorable effect on PMD compensation.
