Single and Double-vortex Vector Solitons in Self-focusing Nonlinear Media

Salgueiro, J; Kivshar, Yuri


Single- and double-vortex vector solitons carrying an angular momentum and propagating in a self-focusing saturable nonlinear medium were analyzed. The existence domains of these vector solitons were calculated and their stability to weak perturbations was also studied. It was also demonstrated that a large-amplitude guided mode can stabilize the ringlike vortes beam which decays due to azimuthal modulational instability. Different types of vector vortex solitons were identified and both vortex...[Show more]
