Figure 1 | Design of on-chip metasurface. a, Principle of phase modulation of diatomic structure based on geometric phase and detour phase. Simulated phase shift map of b, left circularly polarized and c, right circularly polarized output channel as a function of rotation angle θ and displacement δx. d, Optical microscope image of the fabricated on-chip metasurface on top of LN waveguide crossing. e, Scanning electron microscope images of the on-chip metasurface. f, Simulated and measured four-channel holographic images under TE0 mode illuminations along x and y directions along with LCP and RCP analyzers. The double-headed arrows correspond to the polarization state of the input TE0 mode and the circular arrows represent the polarization state of the analyzer.
