摘要
为了满足评价系统中光器件的光学偏振相关效应(OPRE)所需标准偏振激光光源的需要,本文提出一种新型的偏振态发生器(PSG)的实现方法,使用激光光源、线性起偏器、可旋转的1/4波片(QWP)和可旋转的1/2波片(HWP)的组合实现任意偏振态激光的产生。利用一种简便的二维平面几何方法,从理论上分析了该方案的正确性,并推导出了相应的控制算法。实验结果表明,该PSG可以提高精度产生任意偏振态,并且具有成本低、易于实现和控制算法简单等优点。
A novel polarization state generator（PSG） is presented which can realize arbitrary state of polarization（SOP） output light. The PSG consists of a linear polarizer, a rotatable quarter-waveplate（QWP） and a rotatable half-waveplate （HWP）. The operating principles and controlling algorithms for this PSG are derived through a new 2-dimensional geometry method. The experimental results show that the PSG can produce arbitrary,high accurate SOP output light. This PSG can be used in the field of testing the impact of polarization related effects on optical components and on optical fiber communication systems.
