Optical Vortices: folding and twisting waves of light

Abstract

An overview of exciting research in the field of nonlinear singular optics was presented. Optical vortices provided an efficient way to control light by creating reconfigurable waveguides in bulk media. Theoretical analysis of two color parametric optical vortices demonstrated that such vortices possess unexpected properties that make them more exotic than quantized vortices in unconventional superfluids.
