Fiber-based photonic structures generate zeroth-order and vortex Bessel beams

Bessel beams are fascinating because they have special advantages over typical Gaussian beams in optics. They propagate diffraction-free and have self-healing properties. That’s why Bessel beams have a great potential in optical tweezers, microscopy, spectroscopy and communications applications. However, the generation of Bessel beams is challenging because it relies on space-consuming optics and is limited to meet the need of customized beam parameters. Using Nanoscribe’s Two-Photon Polymerization technology, novel photonic structures were developed and 3D-printed on a fiber by scientists at the King Abdullah University of Science and Technology. The photonic structures are capable of generating zeroth-order and vortex
