Three‐Channel Wavefront Shaping Using Non‐Interleaved Spin‐Multiplexed Plasmonic Metasurfaces
https://orcid.org/0000-0001-7362-519X
AbstractMetasurfaces have garnered significant attention for their ability to manipulate light waves with multifunctional capabilities. Integrating independent wavefront controls within a single metasurface is essential to meet the growing demand for high‐capacity, flat photonic devices. In this work, a versatile non‐interleaved plasmonic metasurface platform utilizing quarter‐wave plate meta‐atoms for independent and simultaneous phase modulation of both co‐ and cross‐polarized circularly polarized waves with subwavelength pixels, achieved by merging resonance and Pancharatnam‐Berry phases is presented. We propose and experimentally validate three proof‐of‐concept designs operating in the near‐infrared range: a beam deflector with three distinct reflection angles, a focusing metalens with three focal lengths, and a vortex beam generator with tunable topological charges. This plasmonic metasurface platform paves the way for customizable, multi‐channel functionalities, advancing the development of integrated photonic devices with enhanced versatility.
