Abstract

We report a method of generating exotic optical polarization Möbius strips through tightly focusing an arbitrary vector beam. A heart-shaped Möbius strip, an "8"-shaped twin Möbius strip, and a circular Möbius strip with varying polarization twisting rate are demonstrated. The ability of tailoring three-dimensional optical polarization topologies may spur novel studies of optics and physics and find their applications in sensing, light coupling to nanostructures, light-matter interaction, and metamaterial fabrication.

摘要

我们报告了一种通过紧密聚焦任意矢量光束来生成奇异光学偏振莫比乌斯带的方法。展示了一个心形莫比乌斯带、一个“8”字形双莫比乌斯带以及一个具有变化偏振扭转率的圆形莫比乌斯带。定制三维光学偏振拓扑结构的能力可能会激发光学和物理学的新研究，并在传感、光与纳米结构的耦合、光与物质相互作用以及超材料制造中找到其应用。
