高阶矢量Bessel涡旋光的传输和自愈特性研究
Research on transmission and self-healing characteristics of high-order vector Bessel vortex beams
摘要
Abstract
High-order vector Bessel vortex beams,due to their non-diffracting,self-healing properties and the simultaneous presence of anisotropic vortex polarization distribution and helical phase on their cross-sections,have significant application potential in fields such as information transmission,imaging,anti-in-terference,and particle manipulation.This paper,based on the mode extraction principle and optical pen technology,replaced the traditional method of generating high-order vector Bessel vortex beams by modu-lating two separate beams.It simulated and experimentally verified the generation of high-order vector Bessel vortex beams from a single incident beam,and studied their transmission characteristics and self-healing properties in free space.Additionally,taking the topological charge and the vortex order of the vec-tor Bessel vortex beam as 0,1,and 2 respectively,the influences of the two on the transmission and self-healing properties of the vector Bessel vortex beam were compared and analyzed.Both numerical simula-tions and optical experiments showed that during beam transmission,the order of the vortex beam and the topological charge did not affect the non-diffracting state of maintaining the central region's light intensity from diverging;after encountering obstacles that disrupted propagation,beams with smaller topological charges required less time for self-healing.This has important potential significance for application re-search in optical trapping,optical imaging,optical communication,and other fields.关键词
