Generation of rotation-varying 3D Helical structured light fields via counter-propagating phase-modulated Bessel beams
Abstract
Interference between two counter-propagating Bessel beams typically yields a rotationally invariant three-dimensional (3D) helical structured light field. In this study, we demonstrate that introducing additional phase factors to each beam enables the generation of a 3D helical field with rotation-varying transverse intensity distributions as it evolves along the z-axis. Through numerical simulations, we systematically examine how topological charges and phase factors govern the evolving characteristics by modulating the total phase difference between the beams. The resulting tunable structured light offers potential applications in optical micromanipulation where tailored rotating helical fields are required.
