Abstract
The conventional way of generating Bessel beams (BBs) is based on axicon and other diffractive optical elements such as light modulators. These methods involve space-consuming optics. To overcome this limitation, over the past years, efforts were made to create BBs using miniaturized optics and generation of BBs directly from optical fibers. We propose a novel photonic structure 3D micro-printed on the end-face of an optical fiber, generating BBs of various orders. With our approach, we report for the first time the generation of high-order BBs from optical fibers. The results showcase Bessel beams ranging from orders zero- to 20.
