Abstract

Photonic orbital angular momentum (OAM) carried by optical vortex has emerged as a fundamental degree of freedom in modern optics, revolutionizing applications from high-capacity communications to quantum information processing. Recently, the manipulation of novel optical vortices has attracted widespread attention and found numerous applications. Here, we demonstrate a kind of superposed cylindrical vector optical field (SC-VOF), and achieve flexible manipulated longitudinal polarization vortices in focal plane. By selecting different parameters of the SC-VOF, the one-, two-, and three-dimensional longitudinal polarization vortices are generated, and the topological charge and photonic OAM can be flexibly manipulated. The flexible manipulation of longitudinal polarization vortices, featuring arbitrary topological charges and controllable photonic OAM, enables a wide range of cutting-edge applications, including high-resolution fluorescent imaging, enhanced Raman spectroscopy, and advanced optical tweezers in both scientific research and industrial technologies.
