    Systematic results are reported for dynamics of circular patterns (“necklaces”), composed of fundamental solitons and carrying orbital angular momentum, in the two-dimensional model, which describes the propagation of 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)

    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 ...
