Spatiotemporal manipulation of three-dimensional vectorlight fields

Abstract

<p indent=0mm>Vector light fields show many exotic phenomena and applications that do not exist in scalar light fields, but current research of polarization optics mainly focuses on two-dimensional polarization manipulation. Recently, researchers have proposed a novel spatiotemporal manipulation method of synthetic vector light fields based on metasurfaces with asymmetric photonic spin-orbit interactions, which can in principle produce arbitrary three-dimensional vector light fields. This method expands polarization optics from two-dimensional space to three-dimensional space, provides some new ideas for the research of vector light field manipulation and its property in long-distance energy and information transmission, and has application prospects in the fields of focal field manipulation, light force control, laser communication, laser processing, etc.
