  • Vortex lattice solitons supported by localized gain 

    Kartashov, Yaroslav V.; Konotop, Vladimir V; Vysloukh, Victor A.; Torner Sabata, Lluís (2010-10-01)
    Article
    Restricted access - publisher's policy
    We 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
    Restricted access - publisher's policy
    We 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
    Restricted access - publisher's policy
    We 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
    Restricted access - publisher's policy
    We 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 ...
