Paper Abstract

Focusing properties of the vector vortex-bearing beams are investigated theoretically by vector diffraction theory. Simulation results show that the intensity distribution in focal region can be altered considerably by adjusting topological charge m and the numerical aperture(NA) of the focusing optical system. Focal pattern evolves from one focal spot to two overlapped intensity peaks1.The two overlapped intensity peaks separate with increasing topological charge m, which leads to the focal splitting. And focal split appears in focal evolution show that the topological charge of the vector vortex-bearing beams influences the focal intensity distribution considerably, and some novel focal patterns appear.
