Query: Trichromatic and Tri-polarization-channel Holography with
  Non-interleaved Dielectric Metasurface   Metasurfaces hold great potentials for advanced holographic display with
extraordinary information capacity and pixel sizes in an ultrathin flat
profile. Dual-polarization channel to encode two independent phase profiles or
spatially multiplexed meta-holography by interleaved metasurfaces are
captivated popular solutions to projecting multiplexed and vectorial images.
However, the intrinsic limit of orthogonal polarization-channels, their
crosstalk due to coupling between meta-atoms, and interleaving-induced
degradation of efficiency and reconstructed image quality set great barriers
for sophisticated meta-holography from being widely adopted. Here we report a
non-interleaved TiO2 metasurface holography, and three distinct phase profiles
are encoded into three orthogonal polarization bases with almost zero
crosstalk. The corresponding three independently constructed intensity profiles
are therefore assigned to trichromatic (RGB) beams, resulting in high-quality
and high-efficiency vectorial meta-holography in the whole visible regime. Our
strategy presents an unconventionally advanced holographic scheme by
synergizing trichromatic colors and tri-polarization channels, simply realized
with a minimalist non-interleaved metasurface. Our work unlocks the
metasurface's potentials on massive information storage, polarization optics,
polarimetric imaging, holographic data encryption, etc.
