Light-induced waveguide by a finite self-trapped vortex beam in a photorefractive medium

Abstract : We report the formation of a 2D waveguide induced by a self-trapped vortex beam in a photorefractive-photovoltaic medium. Demonstrations are performed by monitoring the self-trapping dynamic of an annular vortex beam in a LiNbO(3):Fe crystal. Control of the experimental observations is consistent with the underlying physics revealed by a numerical model.
