Coupled-mode theory for spatial gap solitons in optically-induced lattices
Boris A. Malomed, Elena A. Ostrovskaya, Yuri S. Kivshar
We develop a coupled-mode theory for spatial gap solitons in the one-dimensional photonic lattices induced by interfering optical beams in a nonlinear photorefractive crystal. We d…
Second-harmonic generation in vortex-induced waveguides
José R. Salgueiro, Andreas Carlsson, Elena Ostrovskaya +1
We study the second-harmonic generation and localization of light in a reconfigurable waveguide induced by an optical vortex soliton in a defocusing Kerr medium. We show that the v…
Observation of discrete vortex solitons in optically-induced photonic lattices
Dragomir N. Neshev, Tristram J. Alexander, Elena A. Ostrovskaya +4
We report on the frst experimental observation of discrete vortex solitons in two-dimensional optically-induced photonic lattices. We demonstrate strong stabilization of an optical…
Band-gap solitons in nonlinear optically-induced lattices
Anton S. Desyatnikov, Elena A. Ostrovskaya, Yuri S. Kivshar +1
We introduce novel optical solitons that consist of a periodic and a spatially localized components coupled nonlinearly via cross-phase modulation. The spatially localized optical…
Spatial Solitons in Optically-Induced Gratings
Dragomir Neshev, Elena Ostrovskaya, Yuri Kivshar +1
We study experimentally nonlinear localization effects in optically-induced gratings created by interfering plane waves in a photorefractive crystal. We demonstrate the generation…
Multi-soliton energy transport in anharmonic lattices
Elena A. Ostrovskaya, Serge F. Mingaleev, Yuri S. Kivshar +2
We demonstrate the existence of dynamically stable multihump solitary waves in polaron-type models describing interaction of envelope and lattice excitations. In comparison with th…
Observation of dipole-mode vector solitons
Wieslaw Krolikowski, Elena A. Ostrovskaya, Carsten Weilnau +5
We report on the first experimental observation of a novel type of optical vector soliton, a {\em dipole-mode soliton}, recently predicted theoretically. We show that these vector…
Multi-component optical solitary waves
Yuri S. Kivshar, Andrey A. Sukhorukov, Elena A. Ostrovskaya +5
We discuss several novel types of multi-component (temporal and spatial) envelope solitary waves that appear in fiber and waveguide nonlinear optics. In particular, we describe mul…
