Interlaced linear-nonlinear optical waveguide arrays
Kyriakos Hizanidis, Yannis Kominis, Nikolaos K. Efremidis
The system of coupled discrete equations describing a two-component superlattice with interlaced linear and nonlinear constituents is revisited as a basis for investigating binary…
Analytic theory of narrow lattice solitons
Y. Sivan, G. Fibich, N. K. Efremidis +1
The profiles of narrow lattice solitons are calculated analytically using perturbation analysis. A stability analysis shows that solitons centered at a lattice (potential) maximum…
Three-dimensional vortex solitons in self-defocusing media
Nikolaos K. Efremidis, Kyriakos Hizanidis, Boris A. Malomed +1
We demonstrate that families of vortex solitons are possible in a bi-dispersive three-dimensional nonlinear Schrodinger equation. These solutions can be considered as extensions of…
