High-efficiency monolayer metallic metasurface for modulation of orbital angular momentum
文献摘要：
The optical vortex beam has widely been studied and used because of its unique orbital angular momentum[OAM].To generate and control OAM in compact and integrated systems,many metallic metasurface devices have been proposed,however,most of them suffer from the low efficiency.Here,we propose and experimentally verify a high-efficiency mono-layer metallic metasurface composed of semicircular nano-grooves distributed with detour phase.The metasurface can generate single or an array of OAM with spin-sensitive modulation and achieve the maximum efficiency of 60.2％in theory and 30.44％in experiment.This work has great potential in compact OAM detection and communication systems.
