Annotation
Soliton dymanics in Kerr medium with localized nonlinear defect was investigated. Two regimes can be observed: refraction and trapping of the soliton by the inhomogeneity as a result of their interaction. The conditions of the soliton trapping for different shapes of the defect were investigated and it was shown that the defect impact on soliton dynamics is amplified with the increase of the nonlinear coefficient gradient.
