Broadband optical vortex beam generation using flat-surface nanostructured gradient index vortex phase masks

Abstract We developed a new kind of compact flat-surface nanostructured gradient index vortex phase mask, for the effective generation of optical vortex beams in broadband infrared wavelength range. A low-cost nanotechnological material method was employed for this work. The binary structure compone...
