Partially Incoherent Optical Vortices in Self-focusing Nonlinear Media

Jeng, Chien Chung; Shih, MIng-Feng; Motzek, Christian; Kivshar, Yuri


The stable propagation of spatially localized optical vortices in self-focusing nonlinear media was investigated. The optical vortices were created by partially incoherent light beams which propagated in a photorefractive nonlinear medium and carried a phase dislocation. The single-charge and double-charge optical vortices were stabilized in self-focusing nonlinear media when the value of the spatial incoherence of light exceeded a certain threshold. The results show that the vortex...[Show more]
