Soliton modes, stability, and drift in optical lattices with spatially modulated nonlinearity Kartashov, Yaroslav V. Vysloukh, Victor A. Torner Sabata, Lluís Universitat Politècnica de Catalunya. Departament de Teoria del Senyal i Comunicacions Universitat Politècnica de Catalunya. FOTONICA - Grup de Recerca de Fotònica Àrees temàtiques de la UPC::Enginyeria de la telecomunicació::Telecomunicació òptica::Fotònica Photonics Optical communications Fotònica Comunicacions òptiques We put forward new properties of lattice solitons in materials and geometries where both the linear refractive index and the nonlinearity are spatially modulated. We show that the interplay between linear and out-of-phase nonlinear refractive index modulations results in new soliton properties, including modifications of the soliton stability and transverse mobility, as well as shape transformations that may be controlled, e.g., by varying the light intensity.
