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.本文对国内外十余种偏振控制器的组成和原理进行了分析,最后对各种偏振控制器的性能作了比较,并评价了它们的应用前景.
The polarization direction of signal is required to match with that of local oscillator. This essay introduces more than ten kinds of polarization controllers emerged so far. The emphasis is placed on their components and theories.Finally, we compare various polarization handling methods and analyze their application prospects.
