Halogen-perovskite metasurfaces for trichromatic channel color holographic imaging

Halogen perovskites have high refractive indexes and adjustable bandgaps, making them promising materials for all-dielectric and tunable metasurfaces. Herein, we design tunable polarization-converted halogen-perovskite metasurfaces and explained their characteristics in theory by using the Jones matrix. We propose a halogen-perovskite color holographic metasurface with low crosstalk owing to the excellent monochromatic permeability of three halogen perovskites (MAPbCl(3): 450 nm; MAPbBr(3): 550 nm; MAPbI(3): 740 nm). In addition, we build three independent imaging channels to prevent color crosstalk between them to achieve fantastic imaging applications. This study serves as a good reference for research on optical information storage, polarization optics, holographic image encryption.
