Abstract: We theoretically investigate the generation and detection of multi-channel vortex beams (VBs) carrying multiple orbital angular momenta by a monolayer all-dielectric metasurface. The metasurface can realize simultaneous manipulation of a two-level amplitude and continuous phase… read more here.
