Abstract-Multiplexing THz vortex beams with a single diffractive 3D printed lens
We present a novel method for experimentally generating multiplexed THz vortex beams by using a single 3D printed element that combines a set of radially distributed spiral phase plates, and a binary focusing Fresnel lens. With this element we have experimentally demonstrated that THz multiplexing can be tailored to fit within a small space on an optical bench. Results are presented beside numerical simulations, demonstrating the robust nature of the experimental method.
