36-Channel Spin and Wavelength Co-Multiplexed Metasurface Holography by Phase-Gradient Inverse Design.

ABSTRACT: Metasurface holography has emerged as a versatile tool for manipulating light at subwavelength scales, offering enhanced capabilities in multiplexing high-resolution holographic images. However, the scalability of channel multiplexing remains a significant challenge. In this paper, a high-capacity single-cell metasurface is presented capable of maximizing channels by multiplexing holographic images across both spin and wavelength using a single-phase map. The achievement of simultaneous multiplexing of left- and right-circular polarization states is detailed across a broad spectral range, from visible to near-infrared wavelengths, by using a single-cell metasurface, optimized through an inverse design to minimize loss between the target and output images by automatic differentiation.
