光学自旋霍尔效应（OSHE）是一种与自旋相关的光输运现象，类似于凝聚态物理中的自旋霍尔效应。尽管这种效应已经被预测和观察了几十年，但由于超材料和超表面的发展，这种效应最近引起了人们的极大兴趣，它们可以为我们提供光-物质相互作用和自旋-轨道相互作用的量身定制控制。与OSHE的发展并行，元表面为我们提供了操纵OSHE以实现更强响应、更高效率、更高分辨率或更多自由度来控制波前的机会。在这里，我们给出了一个概述的OSHE的基础上超表面启用几何相位在不同种类的配置空间和它们的应用自旋相关的光束转向，聚焦，全息图，结构光的产生，和检测。这些发展标志着未来光学元件的自旋光学新时代的开始。
Abstract Optical spin-Hall effect (OSHE) is a spin-dependent transportation phenomenon of light as an analogy to its counterpart in condensed matter physics. Although being predicted and observed for decades, this effect has recently attracted enormous interests due to the development of metamaterials and metasurfaces, which can provide us tailor-made control of the light-matter interaction and spin-orbit interaction. In parallel to the developments of OSHE, metasurface gives us opportunities to manipulate OSHE in achieving a stronger response, a higher efficiency, a higher resolution, or more degrees of freedom in controlling the wave front. Here, we give an overview of the OSHE based on metasurface-enabled geometric phases in different kinds of configurational spaces and their applications on spin-dependent beam steering, focusing, holograms, structured light generation, and detection. These developments mark the beginning of a new era of spin-enabled optics for future optical components.
