Abstract
Vivid images can be created with metasurface color holograms by configuring their subwavelength planar structures. However, it is a challenge to arbitrarily tune the colors of the images after the metasurfaces have been fabricated. The common method of balancing the incident intensities of individual wavelengths directly or indirectly does not change the relative brightness/color of different parts of the image. Here, we use spin manipulation and wavelength multiplexing to change the color of not only the entire holographic image but also of defined parts of it. This is achieved by designing polarization-dependent dual images for each primary color. This work demonstrates potential for exploiting dielectric metasurfaces to reconstruct colorful images, which is highly desired in the holographic display industry.
