Nonlinear localized modes at phase-slip defects in waveguide arrays

By Mario Molina Gálvez and Yuri S. Kivshar

Abstract

We study light localization at a phase-slip defect created by two semi-infinite mismatched identical arrays of coupled optical waveguides. We demonstrate that the nonlinear defect modes possess the specific properties of both nonlinear surface modes and discrete solitons. We analyze the stability of the localized modes and their generation in both linear and nonlinear regimes
