Stable vortex solitons in nonlocal self-focusing nonlinear media.
نویسندگان
چکیده
We reveal that spatially localized vortex solitons become stable in self-focusing nonlinear media when the vortex symmetry-breaking azimuthal instability is eliminated by a nonlocal nonlinear response. We study the main properties of different types of vortex beams and discuss the physical mechanism of the vortex stabilization in spatially nonlocal nonlinear media.

Vortex Solitons and Rotating Azimuthons in Nonlinear Media
We give a brief overview of the recent advances in nonlinear singular optics that studies the propagation and stability of optical vortices in nonlinear media, with the emphasis on the properties of vortex solitons and rotating azimuthons. In general, self-focusing nonlinearity generates the azimuthal instability of vortex beams, but it can support novel types of stable (or metastable) self-tra...
متن کاملStable Vortex Solitons and Robust Soliton Complexes in Optical Media with Competing Nonlinearities
An overview of recent results in the field of vortex (spinning) solitons and soliton complexes composed of several fundamental (nonspinning) solitons in twoand three-dimensional optical media with competing nonlinearities is presented. It is concluded that multidimensional solitons with intrinsic topological charge are stable provided that their internal size and power (energy) are large enough...
متن کاملStabilization of vortex solitons by combining competing cubic-quintic nonlinearities with a finite degree of nonlocality
In contrast to an infinite degree of nonlocality, we demonstrate that vortex solitons in nonlinear media under competing self-focusing cubic and self-defocusing quintic nonlocal nonlinearities can be stabilized with a finite degree of nonlocality. Stable vortex solitons in the upper branch, bifurcated from the competing cubic-quintic nonlinearities, are found to be supported when the original d...
متن کاملTracking azimuthons in nonlocal nonlinear media
We study the formation of azimuthons, i.e., rotating spatial solitons, in media with nonlocal focusing nonlinearity. We show that whole families of these solutions can be found by considering internal modes of classical non-rotating stationary solutions, namely vortex solitons. This offers an exhaustive method to identify azimuthons in a given nonlocal medium. We demonstrate formation of azimut...
متن کامل0 D ec 2 00 5 Stable rotating dipole solitons in nonlocal optical media
Recently increased interest in the study of self-trapped optical beams in nonlocal nonlinear media is explained by experimental observations of nonlocal spatial solitons in liquid crystals and lead glasses as well as a number of many interesting theoretical predictions, including stabilization of vortex solitons against symmetry breaking instability in the media with nonlocal optical response. ...
