Abstract

Metasurface plays an increasing crucial role in photonics applications due to its powerful control of optical fields, multifunctionality, as well as miniaturization. Metasurface holography, as one promising approach of holographic display, has broad prospects in the fields of color display, 3D imaging, Augmented Reality (AR), and Virtual Reality (VR). However, the reported metasurfaces still suffer from problems such as low transmission efficiency and poor imaging quality in the visible wavelengths, giving rise to extremely challenging to further enhance the efficiency of color holographic imaging. To overcome the low efficiency of reported metasurface holograms, we proposed a metasurface unit structure with high polarization conversion efficiency based on reverse design algorithm, and applied it to color holography. By using the particle swarm optimization algorithm and three-dimensional Finite- Difference Time-Domain (FDTD) method, the structural parameters of a single periodic unit on the metasurface were optimized to achieve effective separation of cross-polarized and co-polarized reflected beams in space, resulting in highly efficient, broadband, and stable polarization conversion. The results indicate that, the average efficiency of circular polarization conversion can reach 93% in a wide wavelength range of 480 to approximately 622 nm when the average reflectance of the cross-polarized component circularly polarized exceeds 80%. On this basis, we further demonstrated the application of the metasurface designed by reverse design algorithm to efficient color holographic imaging. We expect that this broadband and efficient metasurface will accelerate the development of metasurfaces for AR and VR.
