  • Vortex nucleation and evolution in parametric wave mixing 

    Molina Terriza, Gabriel; Torner Sabata, Lluís (Institute of Electrical and Electronics Engineers (IEEE), 1999)
    Text en actes de congrés
    Accés obert
    We predict a variety of new phenomena, that includes the spontaneous nucleation of multiple vortex twins, vortex rotation and drift, vortex-antivortex interaction and annihilation, and formation of quasi-aligned patterns ...
  • Three-dimensional topological solitons in PT-symmetric optical lattices 

    Kartashov, Yaroslav V.; Hang, Chao; Huang, Guoxiang; Torner Sabata, Lluís (2016-09-21)
    Article
    Accés obert
    We address the properties of fully three-dimensional solitons in complex parity-time (PT)-symmetric periodic lattices with focusing Kerr nonlinearity, and uncover that such lattices can stabilize both fundamental and ...
  • Ultrasensitive interferometric on-chip microscopy of transparent objects 

    Terborg, Roland A.; Pello, Josselin; Mannelli, Ilaria; Pérez Torres, Juan; Pruneri, Valerio (2016-06)
    Article
    Accés obert
    Light microscopes can detect objects through several physical processes, such as scattering, absorption, and reflection. In transparent objects, these mechanisms are often too weak, and interference effects are more suitable ...
  • Trapping of light beams and formation of spatial solitary waves in quadratic nonlinear media 

    Torner Sabata, Lluís; Torruellas, W; Stegeman, G; Menyuk, C; Wright, E (Institute of Electrical and Electronics Engineers (IEEE), 1996)
    Text en actes de congrés
    Accés obert
    Summary form only given. In this paper we report the outcome of our comprehensive investigations to study the dynamics of the beam trapping in both bulk crystals and optical planar waveguides made of quadratic nonlinear ...
  • Frequency conversion of structured light 

    Steinlechner, Fabian; Hermosa, Nathaniel; Pruneri, Valerio; Pérez Torres, Juan (Macmillan Publishers, 2016-02-15)
    Article
    Accés obert
    Coherent frequency conversion of structured light, i.e. the ability to manipulate the carrier frequency of a wave front without distorting its spatial phase and intensity profile, provides the opportunity for numerous novel ...
  • Weak value amplification: a view from quantum estimation theory that highlights what it is and what isn’t 

    Pérez Torres, Juan; Salazar Serrano, Luis Jose (Macmillan Publishers, 2016-02-01)
    Article
    Accés obert
    Weak value amplification (WVA) is a concept that has been extensively used in a myriad of applications with the aim of rendering measurable tiny changes of a variable of interest. In spite of this, there is still an on-going ...
  • Rotating vortex clusters in media with inhomogeneous defocusing nonlinearity 

    Kartashov, Yaroslav V.; Malomed, Boris A.; Vysloukh, Victor A.; Belic, Milivoj R.; Torner Sabata, Lluís (2017-02-01)
    Article
    Accés restringit per política de l'editorial
    We show that media with inhomogeneous defocusing cubic nonlinearity growing toward the periphery can support a variety of stable vortex clusters nested in a common localized envelope. Nonrotating symmetric clusters are ...
  • A 3D printed toolbox for opto-mechanical components 

    Salazar Serrano, Luis Jose; Pérez Torres, Juan; Valencia, Alejandra (2017-01-18)
    Article
    Accés obert
    In this article we present the development of a set of opto-mechanical components (a kinematic mount, a translation stage and an integrating sphere) that can be easily built using a 3D printer based on Fused Filament ...
  • A measure of flow vorticity with twisted beams of light 

    Belmonte Molina, Aniceto; Rosales Guzmán, Carmelo; Pérez Torres, Juan (Curran, 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    The measurement of vorticity, a parameter providing local measurements of rotation at every point in a flow, would greatly assist research fields as diverse as biology microfluidics, complex motions in the oceanic and ...
  • Vector mixed-gap surface solitons 

    Kartashov, Yaroslav V.; Ye, F; Torner Sabata, Lluís (2006-05)
    Article
    Accés restringit per política de l'editorial
    We elucidate the properties of mixed-gap vector surface solitons supported by the interface between a uniform medium and an optical lattice imprinted in a Kerr-type nonlinear media. The components of such mixed-gap solitons ...
