Caustics of Non-Paraxial Perfect Optical Vortices Generated by Toroidal Vortex Lenses
In this paper, we consider the comparative formation of perfect optical vortices in the non-paraxial mode using various optical elements: non-paraxial and parabolic toroidal vortex lenses, as well as a vortex axicon in combination with a parabolic lens. The theoretical analysis of the action of thes...
