Cover story: Yang R, Yu Q Q, Pan Y W, et al. Directional-multiplexing holography by on-chip metasurface[J]. Opto-Electron Eng, 2022, 49(10): 220177
The on-chip metasurface is introduced into integrated optical waveguides to achieve arbitrary modulation of guided waves, which provides a convenient and versatile platform for the conversion between guided waves and free-space functions. The research propose and experimentally demonstrate aquad-fold multiplexed holographic display optics device based on an on-chip metasurface, guided waves into free space in circular polarization, destroying the phase degeneracy that exists in the wavevector directions with only the detour phase. Moreover, by utilizing simulated annealing phase optimization algorithm and multiplexing, they achieved aquad-fold multiplexed far-field holographic display with independent encoding capability.
