Fig. 2 Broadband full-vectorial hologram with spatially variant polarization states. (a) Schematic illustration of the designed vectorial hologram, where the upper and lower regions are distinctly encoded with customized linear or circular polarization states under LP incident light. (b) Top-view and side-view SEM images of the fabricated metasurface. (c) Simulated and experimentally captured holographic images at wavelengths of 447 nm, 518 nm, and 637 nm, respectively, obtained by placing different polarizers at the output side of the metasurface.
