Rotating vortex solitons supported by localized gain
Borovkova, Olga V.; Lobanov, Valery E.; Kartashov, Yaroslav; Torner Sabata, Lluís (2011-05-15)
Article
Accés restringit per política de l'editorialWe show that ringlike localized gain landscapes imprinted in focusing cubic (Kerr) nonlinear media with strong two-photon absorption support new types of stable higher-order vortex solitons containing multiple phase ... -
Soliton generation by counteracting gain-guiding and self-bending
Lobanov, Valery E.; Kartashov, Yaroslav V.; Vysloukh, Victor A.; Torner Sabata, Lluís (2012-11-01)
Article
Accés restringit per política de l'editorialWe introduce a concept for stable spatial soliton formation, mediated by the competition between self-bending induced by a strongly asymmetric nonlocal nonlinearity and spatially localized gain superimposed on a wide ... -
Solitons supported by spatially inhomogeneous nonlinear losses
Borovkova, Olga V.; Kartashov, Yaroslav; Vysloukh, Victor A.; Lobanov, Valery E.; Malomed, Boris A.; Torner Sabata, Lluís (2012)
Article
Accés restringit per política de l'editorialWe uncover that, in contrast to the common belief, stable dissipative solitons exist in media with uniform gain in the presence of nonuniform cubic losses, whose local strength grows with coordinate η (in one dimension) ... -
Stabilization of spatiotemporal solitons in Kerr media by dispersive coupling
Kartashov, Yaroslav V.; Malomed, Boris A.; Konotop, Vladimir V.; Lobanov, Valery E.; Torner Sabata, Lluís (OSA, 2015-03-11)
Article
Accés obertWe introduce a mechanism to stabilize spatiotemporal solitons in Kerr nonlinear media, based on the dispersion of linear coupling between the field components forming the soliton states. Specifically, we consider solitons ... -

Stable bright and vortex solitons in photonic crystal fibers with inhomogeneous defocusing nonlinearity
Lobanov, Valery E.; Borovkova, Olga V.; Kartashov, Yaroslav V.; Malomed, Boris A.; Torner Sabata, Lluís (2012-06-01)
Article
Accés restringit per política de l'editorialWe predict that a photonic crystal fiber whose strands are filled with a defocusing nonlinear medium can support stable bright solitons and also vortex solitons if the strength of the defocusing nonlinearity grows toward ... -
Stable radially symmetric and azimuthally modulated vortex solitons supported by localized gain
Lobanov, Valery E.; Kartashov, Yaroslav V.; Vysloukh, Victor A.; Torner Sabata, Lluís (2011-01)
Article
Accés restringit per política de l'editorialWe 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 gain in amplifying rings results in the ... -
Stable vortex-soliton tori with multiple nested phase singularities in dissipative media
Borovkova, Olga V.; Lobanov, Valery E.; Kartashov, Yaroslav; Torner Sabata, Lluís (2012)
Article
Accés restringit per política de l'editorialWe show the existence of stable two- and three-dimensional vortex solitons carrying multiple, spatially separated, single-charge topological dislocations nested in a common vortex-ring core. Such nonlinear states are ... -
Topological light bullets supported by spatiotemporal gain
Lobanov, Valery E.; Borovkova, Olga V.; Kartashov, Yaroslav; Vysloukh, Victor A.; Torner Sabata, Lluís (2012-02-02)
Article
Accés restringit per política de l'editorialWe reveal that the competition among diffraction, cubic nonlinearity, two-photon absorption, and gain localized in both space and time results in arrest of collapse, suppression of azimuthal modulation instabilities for ... -
Vortex twins and anti-twins supported by multiring gain landscapes
Borovkova, Olga V.; Kartashov, Yaroslav V.; Lobanov, Valery E.; Vysloukh, Victor A.; Torner Sabata, Lluís (2011-10-01)
Article
Accés restringit per política de l'editorialWe address the properties of multivortex soliton complexes supported by multiring gain landscapes in focusing Kerr nonlinear media with strong two-photon absorption. Stable complexes incorporating two, three, or four ...
