Abstract

Metasurfaces composed of ultrathin subwavelength structures are versatile in manipulating light properties over a wide spectrum range and are promising for integrated optoelectronics for their compactness and compatibility for large volume manufacturing. In this talk I will introduce a simplified binary metasurface, photon sieves, for optical wavefront manipulation for hologram and optical vortex generation, including high tolerance and large angle of view hologram using nano photon sieves, spatial multiplexing of optical angular momentum using plasmonic nanosieves, and arbitrary rational order optical vortex generation using gratings with an aperture.
