Three-Dimensional Light Bullets in Arrays of Waveguides
Stefano Minardi, Falk Eilenberger, Yaroslav V. Kartashov +10
We report the first experimental observation of 3D-LBs, excited by femtosecond pulses in a system featuring quasi-instantaneous cubic nonlinearity and a periodic, transversally-mod…
Soliton shape and mobility control in optical lattices
Yaroslav V. Kartashov, Victor A. Vysloukh, Lluis Torner
We present a progress overview focused on the recent theoretical and experimental advances in the area of soliton manipulation in optical lattices. Optical lattices offer the possi…
Stable two-dimensional solitons in nonlinear lattices
Yaroslav V. Kartashov, Boris A. Malomed, Victor A. Vysloukh +1
We address the existence and stability of two-dimensional solitons in optical or matter-wave media, which are supported by purely nonlinear lattices in the form of a periodic array…
Observation of two-dimensional defect surface solitons
A. Szameit, Y. V. Kartashov, M. Heinrich +7
We report on the experimental observation of two-dimensional solitons located in a defect channel at the surface of a hexagonal waveguide array. The threshold power for the excitat…
Soliton excitation in waveguide arrays with an effective intermediate dimensionality
A. Szameit, Y. V. Kartashov, F. Dreisow +7
We reveal and observe experimentally significant modifications undertaken by discrete solitons in waveguide lattices upon the continuous transformation of the lattice structure fro…
Stabilization of higher-order vortices and multi-hump solitons in media with synthetic nonlocal nonlinearities
Yaroslav V. Kartashov, Victor A. Vysloukh, Lluis Torner
We address the evolution of higher-order excited states, such as vortex and multi-hump solitons, in nonlocal media with synthetic, competing focusing and defocusing nonlinearities…
