摘要
在相干光通信等方面,要求信号光与本地振荡光偏振方向相匹配,这就要求对偏振进行控制。本文介绍了至今国外出现的有关偏振问题的四类解决方案,重点介绍了其中的偏振控制器原理,最后对各种偏振解决方案作了比较并指出了应用前景。
The polarization direction of signal is needed to match with that of local oscillator.This essay introduces four methods having emerged so far. In particulr,the emphasis is placed on the theory about polarization controller (PC). Finally, we compare various polarization handling methods and analyze their prospects.
