Plasmonic nano-slits assisted polarization selective detour phase meta-hologram

Abstract

Traditional detour-phase hologram is a powerful optical device for manipulating phase and amplitude of light, but it is usually not sensitive to the polarization of light. By introducing the light-metasurface interaction mechanism to the traditional detour phase hologram, we design a novel plasmonic nano-slits assisted polarization selective detour phase meta-hologram, which has attractive advantages of polarization multiplexing ability, broadband response, and ultra-compact size. The meta-hologram relies on the dislocations of plasmonic slits to achieve arbitrary phase distributions, showing strong polarization selectivity to incident light due to the plasmonic response of deep-subwavelengt..
