Stable spinning optical solitons in two and three dimensions

Mihalache D.

Opto-Electronics Review

2005

Vol. 13, No. 2

123-127

A brief overview of recent results in the field of multidimensional spinning (vortex) optical solitons is given. We address the stability problem of two- and three-dimensional spinning solitons in media with competing nonlinearities. We conclude that these solitons could be stable, provided that their external size and power (energy) are large enough. The stability of vorticity-carrying solitons is a generic feature of media with competing self-focusing and self-defocusing nonlinearities.
