Abstract

Abstract : Light beams carrying spin angular momentum (SAM) and orbital angular momentum (OAM) have created novel opportunities in the areas of optical communications, imaging, micromanipulation, and quantum optics. In article number 2000062, Ting Xu, Yanqing Lu, and co‐workers demonstrate an efficient detection approach for measuring multiple SAM and OAM modes simultaneously through a planar nanophotonic demultiplexer based on an all‐dielectric metasurface. The ultracompact multifunctional architecture is envisioned to enable simultaneous manipulation and measurement of polarization and spin encoded photon states.
