Vector vortex beams, characterized by their orbital angular momentum and non-uniform polarization distribution, have gained significant attention in the field of optics and photonics due to their unique properties and versatile applications. Existing methods for the generation of arbitrary vector vortex beams often involve complex optical setups or intricate fabrication methods. In this letter, we propose a novel and simplified approach efficient generation of vector vortex beams using polarization multiplexed holograms, fabricated on azo-carbazole polymer using a double exposure technique. This method allows for seamless traversal across the entire Higher-order Poincaré sphere simply by modulating the polarization of a beam that reads the hologram. By employing this technique, we can generate arbitrary vector vortex beams without relying on intricate optical setups, showcasing its potential for diverse applications in optics and photonics.
