摘要

近年来,圆柱矢量光束(CVB)得到了广泛的研究和应用。然而,许多 CVB 生成方法都存在系统复杂、需要大尺寸器件等问题。在这里,我们提出了一种由自旋敏感单元单元组成的单层手性元表面,它可以根据几何相位和迂回相位的组合调制,生成左旋和右旋偏振的不同全息图。在线性偏振入射光束的作用下,元表面可以产生具有可控偏振角和阶数的 CVB,甚至更复杂的矢量光束。这项工作为设计用于产生任意矢量光束的微型光学设备提供了新思路。

Monolayer Chiral Metasurface for Generation of Arbitrary Cylindrical Vector Beams
The cylindrical vector beam (CVB) has been widely studied and applied in recent years. However, many CVB generation methods suffer from complex systems, and large-size devices are required. Here, we propose a monolayer chiral metasurface composed of spin-sensitive unit cells which can generate different holograms for left- and right-circular polarization based on the combined modulation of geometric phase and detour phase. With a linearly polarized incident beam, the metasurface can generate CVBs with controllable polarization angles and orders, and even more complex vector beams. This work provides a new idea for the design of miniaturized optical devices for generating arbitrary vector beams.

期刊介绍: Photonics (ISSN 2304-6732) aims at a fast turn around time for peer-reviewing manuscripts and producing accepted articles. The online-only and open access nature of the journal will allow for a speedy and wide circulation of your research as well as review articles. We aim at establishing Photonics as a leading venue for publishing high impact fundamental research but also applications of optics and photonics. The journal particularly welcomes both theoretical (simulation) and experimental research. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files and software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
