  • Nonlinear hybrid guided waves in birefringent media 

    Pérez Torres, Juan; Torner Sabata, Lluís; Lederer, F.; Mihalache, Dumitru; Baboiu, Daniel; Ciumac, Mariana (1994-06)
    Article
    Restricted access - publisher's policy
    The waveguiding properties of nonlinear hybrid waves guided by integrated-optics structures containing both birefringent crystals and isotropic nonlinear media have been investigated. The existence of both TE- and TM-dominant ...
  • Soliton excitation in waveguide arrays with an effective intermediate dimensionality 

    Szameit, Alexander; Kartashov, Yaroslav V.; Dreisow, Felix; Heinrich, Matthias; Pertsch, T; Nolte, Stefan; Tunnermann, A F Lederer; Vysloukh, Victor A.; Lederer, F.; Torner Sabata, Lluís (2009-01)
    Article

    We reveal and observe experimentally significant modifications undertaken by discrete solitons in waveguide lattices upon the continuous transformation of the lattice structure from one-dimensional to two-dimensional. Light ...
  • Stable spinning optical solitons in three dimensions 

    Mihalache, D D Mazilu I Towers; Mazilu, Dumitru; Crasovan, L.C.; Towers, I.; Buryak, A.V.; Malomed, Boris A.; Torner Sabata, Lluís; Pérez Torres, Juan; Lederer, F. (2002-02)
    Article

    We introduce spatiotemporal spinning solitons (vortex tori) of the three-dimensional nonlinear Schrödinger equation with focusing cubic and defocusing quintic nonlinearities. The first ever found completely stable ...
  • Stable three-dimensional spatiotemporal solitons in a two-dimensional phototnic lattice 

    Mihalache, Dumitru; Mazilu, Dumitru; Lederer, F.; Kartashov, Yaroslav V.; Crasovan, L.C.; Torner Sabata, Lluís (2004-11)
    Article
    Restricted access - publisher's policy
    We investigate the existence and stability of three-dimensional spatiotemporal solitons in self-focusing cubic Kerr-type optical media with an imprinted two-dimensional harmonic transverse modulation of the refractive ...
