Radially symmetric and azimuthally modulated vortex solitons supported by localized gain
Valery E. Lobanov, Yaroslav V. Kartashov, Victor A. Vysloukh +1
We discover that a spatially localized gain supports stable vortex solitons in media with cubic nonlinearity and two-photon absorption. The interplay between nonlinear losses and g…
Light bullets by synthetic diffraction-dispersion matching
Valery E. Lobanov, Yaroslav V. Kartashov, Lluis Torner
We put forward a new approach to generate stable, fully three-dimensional light bullets, which is based on the matching of the intrinsic material dispersion with a suitable effecti…
Inhibition of light tunneling for multichannel excitations in longitudinally modulated waveguide arrays
Valery E. Lobanov, Victor A. Vysloukh, Yaroslav V. Kartashov
We consider evolution of multichannel excitations in longitudinally modulated waveguide arrays where refractive index either oscillates out-of-phase in all neighboring waveguides o…
