Metasurface is emerging as an important platform to design various functional devices due to the superior capability in controlling amplitude, phase and polarization of light through its ultrathin engineering interface. A polarized-selective hologram of all-dielectric metasurface is proposed to reconstruct multiplexed holographic images on different linear polarization status. Unlike early metasurfaces composed of plasmonic resonators with great ohmic loss at visible spectrum, the designed metasurface made of silicon nanoblocks supports a broader spectral response over the bandwidth from 600 to 760 nm with high diffraction efficiency and low crosstalk between different polarization states. Both simulation and experiment have demonstrated the feasibility and adjustability of the polarization-multiplexed metasurface hologram. We believe it will have significant technological potential in the design of optical functional devices.
