    Abstract

    Metasurfaces have shown great promise for the control of optical wavefronts, thus opening new pathways for the development of efficient flat optics. In particular, Huygens' metasurfaces based on all-dielectric resonant meta-atoms have already shown a huge potential for practical applications with their polarization insensitivity and high transmittance efficiency. Here, we experimentally demonstrate a polarization-insensitive holographic Huygens' metasurface based on dielectric resonant meta-atoms capable of complex wavefront control at telecommunication wavelengths. Our metasurface produces a hologram image in the far-field with 82% transmittance efficiency and 40% imaging efficiency. Such efficient complex wavefront control shows that Huygens' metasurfaces based on resonant dielectric meta-atoms are a big step toward practical applications of metasurfaces in wavefront design related technologies, including computer-generated holograms, ultrathin optics, security, and data storage devices.
