A novel method for generating grafted perfect vector vortex beams

Grafted Perfect Vector Vortex Beams (GPVVBs), characterized by their unique amplitude, composite phase, and vectorial polarization structures, exhibit significant potential in fields such as optical manipulation and communication. Conventional generation methods often suffer from bulky systems, high costs, and complex fabrication processes, which limit their integrated applications. To address this challenge, this study proposes a novel and efficient method for generating GPVVBs by leveraging the multi-dimensional modulation capabilities of polarization holography. An integrated holographic device is fabricated by recording a stitched hologram on a photo-anisotropic medium through multiple exposures. The target GPVVB can be reconstructed upon illumination by a single plane wave. Simulations have verified the accuracy of the topological charges and polarization orders of the generated beams. This method offers the advantages of low cost, high integration, and controllable size, providing a practical new pathway for generating complex structured light fields. This work deepens the understanding of polarization holography and expands its applications.
