Metasurface-empowered vector light field regulation,detection and application

携带角动量的矢量光场在微粒操控、光通信与显示、光学信息加密、高维量子信息处理等领域具有广阔应用。然而,传统的方法实现矢量光场调控通常需要使用多个级联的光学元件,如螺旋相位板、偏振片、四分之一波片、涡旋波片、空间光调制器等,导致器件体积庞大,不符合未来光子器件集成化的需求。超构表面的快速发展为集成化矢量光场调控器件的实现提供变革性解决方案。本文概述了国内外基于超构表面的矢量光场调控和检测的相关研究进展。在此基础上,系统总结了现阶段超构表面矢量光场在微粒操控、边缘增强成像、全息显示以及机器视觉等领域的应用。最后,我们对全文进行了总结和讨论,并提出超构表面矢量光场所面临的挑战和未来发展方向。

The vector light field carrying angular momentum finds wide applications in various fields,such as particle manipulation,optical communication and display,optical information encryption,and high-dimensional quantum information processing.However,the conventional approach to vector light field regulation typically involves a series of cascaded optical elements,such as spiral phase plates,polarizers,quarter wave plates,vortex wave plates,spatial light modulators,etc.,resulting in a bulky device that does not meet the requirements for future photonic device integration.The rapid development of metasurfaces offers a transformative solution for realizing integrated meta-devices for vector light field control.In this paper,we summarize the research progress on metasurface-based control and detection of vector light fields.Then,we systematically summarize the current applications of metasurface-based vector light fields in particle manipulation,edge enhancement imaging,holographic display,machine vision,and so on.Finally,we have summarized and discussed the full text as well as the challenges and provided an outlook on this emerging field.
