Supermode spatial solitons via competing nonlocal nonlinearities

Pawel Stanislaw Jung, Miroslaw Karpierz, Marek Trippenbach, Demetrios Christodoulides, Wieslaw Krolikowski


We study spatial soliton formation in a system with competing nonlinearities. In doing so, we consider a specific nonlinear response that involves both focusing and defocusing nonlocal contributions. We demonstrate that at a sufficiently high input power level, the interplay between these nonlocal nonlinearities may lead to the formation of in-phase, two-hump, fundamental spatial solitons. The conditions required for the existence of these two-peak spatial solitons are also presented.
