Abstract

The study of optical vortices and their polarization dynamics has gained significant attention due to their application in advanced optical technologies. Optical vortices, characterized by their unique polarization states, are generated through the manipulation of light’s orbital angular momentum (OAM). This research explores the generation and manipulation of optical vortices using novel techniques, such as plasmonic metafibers and mode conversion, to create pulsed polarized vortex beams (PVB). These beams exhibit advanced characteristics that enhance laser processing, surface excitation, and high-speed communication systems. The study aims to understand the effects of polarization dynamics on vortex formation and to develop efficient methods for controlling these dynamics. The findings demonstrate how variations in spatiotemporal properties, such as the offset of splicing and the period of metafibers, influence the performance of pulsed PVB. This research opens new avenues for designing and controlling laser systems with specialized beam properties, contributing to fields like optical communications, medical imaging, and materials processing.
