Soliton generation by counteracting gain-guiding and self-bending
Soliton generation by counteracting gain-guiding and self-bending
We introduce a new concept for stable spatial soliton formation, mediated by the competition between self-bending induced by a strongly asymmetric nonlocal nonlinearity and spatially localized gain superimposed on a wide pedestal with linear losses. When acting separately both effects seriously prevent stable localization of light, but under suitable conditions …
