Metasurface-enabled holography holds vital applications in various fields such as optical display, optical data storage, and optical encryption. Despite the rapid development of multiplexed metaholograms through exploiting different physical dimensions of photons such as polarization, amplitude, wavelength, and angular momentum, the multiplexing channel is approaching its limit due to the almost exhausted existing physical dimensions of photons. Here we demonstrate the higher-order Poincaré sphere (HOPS)-multiplexed holography by exploiting ve...
