Mobility of high-power solitons in saturable nonlinear photonic lattices
Uta Naether, Rodrigo A. Vicencio, Milutin Stepić
We theoretically study the properties of one-dimensional nonlinear saturable photonic lattices exhibiting multiple mobility windows for stationary solutions. The effective energy b…
Bulk and surface localized states on a magnetic nonlinear impurity
Mario I. Molina
We study localized modes on a single magnetic impurity positioned in the bulk or at the surface of a one-dimensional chain, in the presence of a magnetic field acting at the im…
Control of wavepacket spreading in nonlinear finite disordered lattices
Rodrigo A. Vicencio And Sergej Flach
In the absence of nonlinearity all normal modes (NMs) of a chain with disorder are spatially localized (Anderson localization). We study the action of nonlinearity, whose strength…
Interface solitons in two-dimensional photonic lattices
Mario I. Molina, Yuri S. Kivshar
We analyze localization of light at the interface separating square and hexagonal photonic lattices, as recently realized experimentally in two-dimensional laser-written waveguide…
Nonlinear localized modes at phase-slip defects in waveguide arrays
Mario I. Molina, Yuri S. Kivshar
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…
Surface solitons in two-dimensional chirped photonic lattices
Mario I. Molina, Yaroslav V. Kartashov, Lluis Torner +1
We study surface modes in semi-infinite chirped two-dimensional photonic lattices in the frame- work of an effective discrete nonlinear model. We demonstrate that the lattice chirp…
