Abstract

Metasurfaces provide a miniaturized and superficial solution for implementing various nanophotonic devices by exploiting their unprecedented ability to spatially tailor the phase, amplitude, and polarization of the incident light. These meta-devices intriguing significant attention from the research community and have become a prominent hotspot for the realization of state-of-the-art on-chip devices. Various types of information can be encoded independently into a single metasurface, strengthening the cutting-edge technology of nanophotonic for practical applications such as holograms, lenses, beam steering, high-density optical storage, and displays. The integration of metasurfaces and holographic technology makes it the most desirous, but many of the presented techniques lack multifunctional capabilities. Here, we proposed a straightforward strategy for spin manipulation and wavelength multiplexing via geometric phase to overcome the limitations of multifunctionality through anisotropic nanoantennas in the ultraviolet regime. The proposed design methodology provides a superior degree of freedom to increase the multifunctional capabilities of metasurfaces for independent wavefront manipulation. By simultaneously controlling the polarization of the incident and transmitted wave vector, a trifunctional all-dielectric metasurface is implemented. For the proof of concept, we designed a structure that displays two holograms at focal planes. The proposed metasurface features the nanostructured pixels of the silicon nitride material, a lossless, high-refractive index dielectric material that ensures high transmission efficiency in the ultraviolet regime. It is expected that the proposed design strategy can be applied to broaden the horizon for implementing multifunctional nanophotonic devices and multiple optical phenomena.
