Soliton generation by counteracting gain-guiding and self-bending

TL;DR

This paper presents a novel method for stable spatial soliton formation by balancing self-bending effects and localized gain, resulting in robust solitons that are resilient across various conditions.

Contribution

It introduces a new concept where competing nonlinear effects enable stable soliton formation, overcoming limitations of individual effects.

Findings

Stable solitons form through the balance of self-bending and gain.

Solitons act as attractors over diverse material and input conditions.

Counteracting effects enable robust localization of light.

Abstract

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 they counteract each other, forming robust soliton states that are attractors for a wide range of material and input light conditions.
