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…
