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…
Soliton stripes in two-dimensional nonlinear photonic lattices
Dragomir Neshev, Yuri S. Kivshar, Hector Martin +1
We study experimentally the interaction of a soliton with a nonlinear lattice. We observe the formation of a novel type of composite soliton created by strong coupling of mutually…
Discrete solitons and soliton-induced dislocations in partially-coherent photonic lattices
Hector Martin, Eugenia D. Eugenieva, Zhigang Chen +1
We investigate the interaction between a light beam and a two-dimensional photonic lattice that is photo-induced in a photorefractive crystal using partially coherent light. We dem…
