Nonlinear optical beams carrying phase dislocations
Anton Desyatnikov, Cornelia Denz, Yuri Kivshar
We describe different types of self-trapped optical beams carrying phase dislocations, including vortex solitons and ring-like soliton clusters. We demonstrate numerically how to c…
Solitonic lattices in photorefractive crystals
M. Petrovic, D. Traeger, A. Strinic +3
Two-dimensional spatial solitonic lattices are generated and investigated experimentally and numerically in an SBN:Ce crystal. An enhanced stability of these lattices is achieved b…
Scattering of dipole-mode vector solitons: Theory and experiment
Wieslaw Krolikowski, Glen McCarthy, Yuri S. Kivshar +4
We study, both theoretically and experimentally, the scattering properties of optical dipole-mode vector solitons - radially asymmetric composite self-trapped optical beams. First,…
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…
