3D-printed fiber-based perfect vortex beam generator
An all-fiber focused perfect vortex beam (PVB) generator is reported and fabricated by using 3D printing technology. The generator is constructed by integrating a designed spiral axicon zone plate (SAZP) on the fiber-end facet. The ring diameters of the generated beams are independent of the topological charges and positively correlated with the wave vectors in the transverse direction. By controlling the axicon angle, the ring diameter can be freely adjusted. The experimental results are consistent with the simulation results, confirming the rationality of the design. These generated PVBs are expected to be useful in applications such as high-capacity fiber-optic communication and multifunctional optical tweezers.
