  • Anisotropy-induced photonic bound states in the continuum 

    Gomis Bresco, Jordi; Artigas García, David; Torner Sabata, Lluís (Nature, 2017-03-20)
    Article
    Accés obert
    Bound states in the continuum (BICs) are radiationless localized states embedded in the part of the parameter space that otherwise corresponds to radiative modes. Many decades after their original prediction1, 2, 3 and ...
  • Self-sustained coherent phonon generation in optomechanical cavities 

    Navarro-Urrios, D.; Gomis-Bresco, Jordi; Alzina, F.; Capuj, N. E.; García, P. D.; Colombano, M. F.; Chavez-Angel, E.; Sotomayor-Torres, C. M. (IOP, 2016-08-18)
    Article
    Accés obert
    Optical forces can set tiny objects in states of mechanical self-sustained oscillation, spontaneously generating periodic signals by extracting power from steady sources. Miniaturized self-sustained coherent phonon sources ...
  • On multidimensional solitons and their legacy in contemporary Atomic, Molecular and Optical physics 

    Malomed, Boris; Torner Sabata, Lluís; Wise, Frank; Mihalache, Dumitru (IOP, 2016-08-22)
    Article
    Accés obert
    This viewpoint relates to an article by B A Malomed, D Mihalache, F Wise, and L Torner (2005 J. Opt. B: Quantum Semiclass. Opt. 7 R53–R72) and was published as part of a series of viewpoints celebrating 50 of the most ...
  • Localization-delocalization wavepacket transition in Pythagorean aperiodic potentials 

    Huang, Changming; Ye, Fangwei; Chen, Xianfeng; Kartashov, Yaroslav V.; Konotop, Vladimir V.; Torner, Lluis (Nature, 2016-09-02)
    Article
    Accés obert
    We introduce a composite optical lattice created by two mutually rotated square patterns and allowing observation of continuous transformation between incommensurate and completely periodic structures upon variation of ...
  • Topological States in Partially-PT -Symmetric Azimuthal Potentials 

    Kartashov, Yaroslav V.; Konotop, Vladimir V.; Torner Sabata, Lluís (APS, 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 ...
  • 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 obert
    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 ...
  • Dynamic versus Anderson wave-packet localization 

    Borovkova, Olga V.; Lobanov, Valery E.; Kartashov, Yaroslav V.; Vysloukh, Victor A.; Torner Sabata, Lluís (APS Physics, 2015-06-18)
    Article
    Accés obert
    We address the interplay between two fundamentally different wavepacket localization mechanisms, namely resonant dynamic localization due to collapse of quasi-energy bands in periodic media and disorder-induced Anderson ...
  • 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 (OSA, 2015-03-11)
    Article
    Accés obert
    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 ...
  • Self-deflecting plasmonic lattice solitons and surface modes in chirped plasmonic arrays 

    Li, Chunyan; Cui, Ran; Ye, Fangwei; Kartashov, Yaroslav V; Torner Sabata, Lluís; Chen, Xianfeng (OSA, 2015-03-04)
    Article
    Accés obert
    We show that chirped metal-dielectric waveguide arrays with focusing cubic nonlinearity can support plasmonic lattice solitons that undergo self-deflection in the transverse plane. Such lattice solitons are deeply ...
  • Nano Guiding of Light Using Dyakonov Waves 

    Takayama, Osamu; Artigas García, David; Torner Sabata, Lluís (OSA, 2014-12-01)
