Highest efficiency grayscale all-dielectric meta-holograms
Metasurfaces are ultra-thin patterned structures that emerged recently as planar metadevices  capable of reshaping and controlling incident light. Many designs and functionalities of metasurfaces suggested so far, are based largely on plasmonic planar structures, however most of these metasurfaces demonstrate low efficiencies in transmission due to losses in their metallic components. In contrast, all-dielectric resonant nanophotonic structures  avoid absorption losses, and can...[Show more]
