Abstract
We have proposed and implemented a scheme for Spiral Phase Plate (SPP) with continuous surface fabrication on fiber tips. By combining Focused Ion Beam-Scanning Electron Microscope (FIB-SEM) system and bitmap (BMP) format processing method, we fabricated a SPP with the topological charge of 1 on the fiber tip, and experimentally analyzed the diffraction and interference properties of the generated vortex beam. The experimental results were in good agreement with the simulation results, which indicated the SPP fabricated by this method had good optical properties and high reliability. This work could be valuable for fiber communication and information encryption.
