We propose a simple, scalable and compact device for efficient generation of multiple vector-vortex beams. The device is a polarization hologram fabricated on a azo functionalized copolymer, using a simple interferometric arrangement. Simply illuminating the fabricated hologram with a collimated beam is enough to generate multiple vector-vortex beams, without the need for any additional optics.
