Abstract

We examine the perturbation effect of loss (or gain) and two-photon absorption on the evolution of optical-vortex solitons. For a small perturbation the vortex soliton is shown to follow an adiabatic evolution. The analytical expression for describing the evolution is presented. We also find that the intensity-dependent loss resulting from the two-photon absorption can be counterbalanced by the constant gain (resulting from Raman effect), to lead to stable stationary propagation of the optical-vortex solitons in the perturbed media.
