摘要
In view of large information capacity of holographic metasurface and wide applications of structured light, the polarization-encoded structured light generation is proposed based on holographic metasurface. The polarization-encoded structured light generators consist of rotated L-shaped nanoholes, and they work under linearly polarized light illumination. The rotated L-shaped nanoholes simultaneously manipulate the intensity, phase, and polarization of light field and generate the structured light composed by multiple perfect vortices with polarization-encoded orbital angular momentum (OAM) modes. The generated polarization-encoded structured lights also behave the incident polarization dependence. The polarization multiplexing performance of holographic metasurface is embodied in both incident and output fields, and it is also verified by the numerical simulations. The designed method can be expanded to construct any transmission or reflection holographic metasurfaces, and the generated structured lights provide more switchable OAM channels. The polarization-encoded structured light and the compact holographic metasurface are benefit to broadening the wide applications of structured lights.
