High-dimensional vectorial metasurface holography

Information and image multiplexing based on the polarization states of the light is a powerful tool that can be easily realized with optical metasurfaces. Here, we have demonstrated a novel method for achieving highdimensional vectorial holography based on birefringent alldielectric metasurfaces to explore the full capacity of polarization. By considering the anisotropy property and extra design freedom of rotation matrix, together with smart multiplexing algorithms for establishing quantified related phase profiles, high-dimensional multichannel polarization multiplexed holograms have been successfully achieved using the simplest nanofin as the building block. Compared to previously demonstrated metasurface multiplexed holograms that can only be switched between two states by two orthogonal polarization for the light, here all combinations within twelve polarization channels in total can be obtained.
