AI 中文摘要
我们展示了如何在一个简单装置中，在没有任何非线性光学材料的情况下，基于由偏振分束器馈入的自配置马赫 - 曾德尔干涉仪来执行光的偏振共轭。这能完全自动消除单束光或模式在具有任意双折射的光学系统（如传统光纤）中传播时的偏振变化。通过使共轭光束反向传播并在源处重建原始偏振来补偿正向经历的偏振变化。我们在不同取向的光纤装置中演示了这种偏振共轭，返回光束的测量偏振消光比为 -30 dB。
英文摘要
We show how to perform polarization conjugation of light in a simple apparatus without any nonlinear optical materials, based on self-configuring Mach-Zehnder interferometers fed by a polarization splitter. This allows us to completely and automatically remove the polarization variations on a single beam or mode propagating through an optical system with arbitrary birefringence, such as a conventional optical fiber, and compensate polarization variations experienced in the forward direction by propagating the conjugated beam back through the system and recreating the original polarization at the source. We demonstrate this polarization conjugation in an optical fiber setup in different orientations with a measured polarization extinction ratio of -30 dB for the returned beam.
