Wearable shows or head-mounted shows (HMDs) have the power to create a digital picture within the area of view of 1 or each eyes. Such shows are the principle platform for quite a few digital actuality (VR) and augmented actuality (AR) primarily based functions. Meta-holographic shows built-in with AR expertise have potential functions within the promoting, media, and healthcare sectors. Within the earlier decade, dielectric metasurfaces emerged as the acceptable alternative for designing compact units for extremely environment friendly shows. Nevertheless, the important issue to restrict the gadget performance is stunted conversion effectivity, slender bandwidth, and dear fabrication procedures. Right here, we suggest a spin-isolated dielectric multi-functional metasurface working at broadband optical wavelengths with excessive transmission effectivity within the ultraviolet (UV) and visual (VIS) regimes. The proposed metasurface contains silicon nitride (Si3N4) primarily based meta-atoms with excessive bandgap, i.e., ~ 5.9 eV, and encoded two holographic part profiles. Beforehand, the a number of holographic data integrated within the metasurfaces utilizing interleaved and layer stacking methods resulted in noisy and low-efficiency outputs. A single planar metasurface built-in with liquid crystal is demonstrated numerically and experimentally to validate the spin-isolated dynamic UV-VIS holographic data at broadband wavelengths. In our opinion, the proposed metasurface can have promising functions in healthcare, optical safety encryption, anti-counterfeiting, and UV-VIS nanophotonics.
