Nonlinear optical lattices with a void impurity
Cristian Mejía-Cortés, J. C. Cardona, Andrey A. Sukhorukov +1
We examine a one-dimensional nonlinear (Kerr) waveguide array which contains a single "void" waveguide where the nonlinearity is identically zero. We uncover a new family of nonlin…
Breathers in PT-symmetric optical couplers
I. V. Barashenkov, Sergey V. Suchkov, Andrey A. Sukhorukov +2
We show that the parity-time (PT) symmetric coupled optical waveguides with gain and loss support localised oscillatory structures similar to the breathers of the classical m…
Optical solitons in -symmetric nonlinear couplers with gain and loss
N. V. Alexeeva, I. V. Barashenkov, Andrey A. Sukhorukov +1
We study spatial and temporal solitons in the symmetric coupler with gain in one waveguide and loss in the other. Stability properties of the high- and low-frequency…
Polychromatic interface solitons in nonlinear photonic lattices
Kristian Motzek, Andrey A. Sukhorukov, Yuri S. Kivshar
We demonstrate that interfaces between two nonlinear periodic photonic lattices offer unique possibilities for controlling nonlinear interaction between different spectral componen…
Discrete surface solitons in semi-infinite binary waveguide arrays
Mario I. Molina, Ivan L. Garanovich, Andrey A. Sukhorukov +1
We analyze discrete surface modes in semi-infinite binary waveguide arrays, which can support simultaneously two types of discrete solitons. We demonstrate that the analysis of lin…
Discrete Nonlinear Schrodinger Equations Free of the Peierls-Nabarro Potential
S. V. Dmitriev, P. G. Kevrekidis, A. A. Sukhorukov +2
We derive a class of discrete nonlinear Schr{ö}dinger (DNLS) equations for general polynomial nonlinearity whose stationary solutions can be found from a reduced two-point algebrai…
