Gaussian-beam excitation of 3d nonlinear waves
Mihalache, Dumitru; Baboiu, Daniel; Mazilu, Dumitru; Torner Sabata, Lluís; Pérez Torres, Juan (1994-07)
Article
Accés restringit per política de l'editorialThe propagation of stationary three-dimensional nonlinear guided waves and of Gaussian beams in a slab waveguide in which the cladding displays both Kerr-law and saturable instantaneous self-focusing nonlinearities is ... -
On the stability of TE0 waves guided by thin films bounded by a nonlinear medium
Torner Sabata, Lluís; Pérez Torres, Juan; Mihalache, Dumitru; Baboiu, Daniel; Mazilu, Dumitru (1993-02)
Article
Accés restringit per política de l'editorialThe authors show that investigations on the stability of nonlinear waves guided by planar structures greatly benefit when the conditions of marginal stability are considered on a suitable restricted parameter space. Relevant ... -
Soliton content with quadratic nonlinearities
Artigas García, David; Torner Sabata, Lluís; Pérez Torres, Juan; Mihalache, Dumitru; Mazilu, Dumitru (Optical Society of American (OSA), 1999)
Comunicació de congrés
Accés obertSummary form only given. Quadratic solitons, that form through cascading in materials with second-order nonlinearities, are a topic of current intense investigation. Solitons have been observed in second harmonic generation ... -
Spatial walking solitons in quadratic nonlinear crystals
Torner Sabata, Lluís; Mihalache, Dumitru; Mazilu, Dumitru; Santos Blanco, M. Concepción; Akhmediev, Nail (Optical Society of America, 1998)
Article
Accés obertWe investigate the properties of the families of spatial walking solitons propagating in planar waveguides made of quadratic nonlinear media under conditions for second-harmonic generation in the presence of Poynting vector ... -
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
Accés restringit per política de l'editorialWe 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

Article
Accés restringit per política de l'editorialWe 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 ...
