    • 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 (2015-03-15)
      Article
      Accés restringit per política de l'editorial
      We 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 ...

    • Suppression and restoration of disorder-induced light localization mediated by PT-symmetry breaking 

      Kartashov, Yaroslav V.; Hang, Chao; Konotop, Vladimir V; Vysloukh, Victor A.; Huang, Guoxiang; Torner Sabata, Lluís (2016-01-12)
      Article
      Accés obert
      We uncover that the breaking point of the PT-symmetry in optical waveguide arrays has a dramatic impact on light localization induced by the off-diagonal disorder. Specifically, when the gain/loss control parameter approaches ...

    • Topological states in partially-PT-symmetric azimuthal potentials 

      Kartashov, Yaroslav V.; Konotop, Vladimir V; Torner Sabata, Lluís (2015-11-04)
      Article
      Accés obert
      We introduce partially-parity-time (pPT)-symmetric azimuthal potentials composed from individual PT-symmetric cells located on a ring, where two azimuthal directions are nonequivalent in a sense that in such potential ...

    • 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'editorial
      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 ...
