Abstract

This paper investigates the generation and manipulation of focused high-order Poincaré sphere vector beams with constant annular intensity profiles and arbitrary phase and polarization distributions using an optical metasurface. The proposed design employs a nanoslit pair unit, consisting of orthogonal rectangular nanoslits arranged according to Fresnel zone plate formula. This configuration enables flexible control of phase and amplitude of wavefield by leveraging geometric and propagation phases under circularly polarized vortex beam illumination. By varying the topological charge l of incidence, the optical path difference d, the rotate order q, and the initial orientation angle α₀ of the nanoslit pairs, this method facilitates the creation of diverse high-order Poincaré sphere vector beams. Both simulations and experiments validate the approach, demonstrating its efficacy and potential applications in polarization optics and light-matter interactions.

期刊介绍： Optical Materials has an open access mirror journal Optical Materials: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The purpose of Optical Materials is to provide a means of communication and technology transfer between researchers who are interested in materials for potential device applications. The journal publishes original papers and review articles on the design, synthesis, characterisation and applications of optical materials. OPTICAL MATERIALS focuses on: • Optical Properties of Material Systems; • The Materials Aspects of Optical Phenomena; • The Materials Aspects of Devices and Applications. Authors can submit separate research elements describing their data to Data in Brief and methods to Methods X.
