[ALPS30-03] 3D metasurface holograms of SiN for multicolor projection
The high 95% diffraction efficiency and 83% transmittance were achieved in 3D metasurface holograms made of SiN high-aspect-ratio nanopillars (1394 nm). It enables observation with the naked eye and the time-division-multiplexing method for multicolor projection.
