Topological dragging of solitons
Kartashov, Yaroslav V.; Vysloukh, Victor A.; Torner Sabata, Lluís (2005-12)
Article
Accés restringit per política de l'editorialWe put forward properties of solitons supported by optical lattices featuring topological dislocations and show that solitons experience attractive and repulsive forces around the dislocations. Suitable arrangements of ... -
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 ... -
Tunable soliton self-bending in optical lattices with nonlocal nonlinearity
Kartashov, Yaroslav V.; Vysloukh, Victor A.; Torner Sabata, Lluís (2004-10)
Article
Accés restringit per política de l'editorialWe address the phenomenon of soliton self-bending in Kerr-type nonlocal nonlinear media with an imprinted transverse periodic modulation of the linear refractive index. We show that the imprinted optical lattice makes ... -
Two-dimensional cnoidal waves in Kerr--type saturable nonlinear media
Kartashov, Yaroslav V.; Vysloukh, Victor A.; Torner Sabata, Lluís (2003-07)
Article
Accés restringit per política de l'editorialWe report theoretically the existence, classification, and basic properties of families of stationary two-dimensional cnoidal-type waves in bulk Kerr-type saturable nonlinear media. The families of two-dimensional cnoidal-type ... -
Two-dimensional solitons at interfaces between binary superlattices and homogeneous lattices
Heinrich, Matthias; Kartashov, Yaroslav; Ramírez, L. P. R.; Szameit, Alexander; Dreisow, Felix; Keil, R; Nolte, Stefan; Tünnermann, Andreas; Vysloukh, Victor A.; Torner Sabata, Lluís (2009-12)
Article
Accés restringit per política de l'editorialWe report on the experimental observation of two-dimensional surface solitons residing at the interface between a homogeneous square lattice and a superlattice that consists of alternating “deep” and “shallow” waveguides. ... -
Two-dimensional solitons in nonlinear lattices
Kartashov, Yaroslav V.; Malomed, B A; Vysloukh, Victor A.; Torner Sabata, Lluís (2009-03)
Article
Accés restringit per política de l'editorialWe 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 of cylinders with self-focusing nonlinearity, ... -
Vortex lattice solitons supported by localized gain
Kartashov, Yaroslav V.; Konotop, Vladimir V; Vysloukh, Victor A.; Torner Sabata, Lluís (2010-10-01)
Article
Accés restringit per política de l'editorialWe show that localized gain supports the existence of dissipative vortex solitons in periodic Kerr media with strong two-photon absorption. Vortex solitons exist in both focusing and defocusing media, with their propagation ... -
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 ... -
Walking-vector-soliton caging and releasing
Kartashov, Yaroslav V.; Vysloukh, Victor A.; Torner Sabata, Lluís (2009-06)
Article
Accés restringit per política de l'editorialWe address the formation and propagation of vector solitons in optical lattices in the presence of anisotropy-induced walk-off between ordinary and extraordinary polarized field components. Stable vector solitons trapped ... -
Wave localization at the boundary of disordered photonic lattices
Szameit, Alexander; Kartashov, Yaroslav V.; Zeil, P.; Dreisow, Felix; Heinrich, Matthias; Keil, R.; Nolte, Stefan; Tünnermann, A.; Vysloukh, Victor A.; Torner Sabata, Lluís (2010-04-15)
Article
Accés restringit per política de l'editorialWe report on the experimental observation of reduced light-energy transport and disorder-induced localization close to a boundary of a truncated 1D disordered photonic lattice. Our observations uncover that a higher level ...
