Abstract
Stable localized ring-shaped solitons with intrinsic vorticity in optical media were analyzed with competing quadratic and self defocusing cubic nonlinearities. Broad ring solitons were shown to be stable both in analyzing eigenvalues of the linearized equations and in direct dynamical simulations. Stable topological solitons were shown to coexist with zero spin solitons in competing nonlinearities model.
