Vortex confinement and bending with nonlocal solitons

Opt Lett. 2014 Feb 1;39(3):509-12. doi: 10.1364/OL.39.000509.

Abstract

We investigate the routing of vortex beams in nonlocal media by means of coaxial, co-propagating spatial optical solitons. By introducing a refractive index perturbation in the form of a localized defect or a dielectric interface, the soliton waveguide can be curved and, therefore, can deviate the collinear vortex, effectively routing it, while preventing its destabilization and breakup.
