摘要:

一个快速和自动化的通用偏振变换方案在自适应光学、量子信息以及几乎所有涉及光-物质和光-光相互作用的应用中具有重要价值。提出了一种利用硅基液晶空间光调制器(LCOS-SLM)对光场进行偏振变换的实验。我们实验演示了均匀偏振光场的逐点转换,实现任意的,空间变化的偏振态。此外,我们证明了具有任意空间变化偏振的光场可以被变换为空间不变的(即,均匀)极化。

英文摘要:

A fast and automated scheme for general polarization transformations holds great value in adaptive optics, quantum information, and virtually all applications involving light-matter and light-light interactions. We present an experiment that uses a liquid crystal on silicon spatial light modulator (LCOS-SLM) to perform polarization transformations on a light field. We experimentally demonstrate the point-by-point conversion of uniformly polarized light fields across the wave front to realize arbitrary, spatially varying polarization states. Additionally, we demonstrate that a light field with an arbitrary spatially varying polarization can be transformed to a spatially invariant (i.e., uniform) polarization.
