Abstract

Metasurface-based vectorial holography can reconstruct images with different polarization states. However, the number of polarization channels in the holographic image is relatively small in traditional methods. Here, we propose and demonstrate a metasurface vectorial hologram which carries infinite polarization channels. It can independently control the holographic pattern and polarization distribution, which can be regarded as two independent storage dimensions. We use a supercell-based metasurface to independently control the complex amplitude of the left-handed circularly polarized and right-handed circularly polarized components of the transmitted light, which then superpose in the observation plane for the vectorial pattern generation. Different from most methods, our approach does not involve complex calculations, and it is suitable for far-field design. We anticipate that it may open avenues for future applications which require arbitrary intensity and polarization control.
