Trapping of discrete solitons by defects in nonlinear waveguide arrays — •Rodrigo Vicencio and Luis Morales — Max-Planck-Institut für Physik Komplexer Systeme

We study the trapping process of moving discrete solitons by linear and nonlinear impurities embedded in a one-dimensional nonlinear cubic array. We show that there exist optimal values for the strength of the impurity and for the angle where a strong trapping is obtained. We introduce a criterion for studying scattering dynamics of localized waves in nonlinear extended systems, where trapping of energy takes place.
