Abstract
Optical vortices have received a lot of attention as stable dark soliton solutions for self-defocusing nonlinear systems as the Nonlinear Schroedinger equation and free-running lasers. In self-focusing media they can exist in the form of a localized solution of a ring, however, it is usually unstable. On the other hand, one can expect that the feedback and dissipation brought by a nonlinear cavity might relax the media requirements and generate stable solutions which, in fact, have been predicted in lasers with saturable absorbers [1], and were observed recently in coupled VCSELs [2]. Vortices in self-focusing Ginzburg-Landau-type models were predicted in [3, 4].
