  • Technique for generating periodic structured light beams using birefringent elements 

    Terborg, Roland A.; Pérez Torres, Juan; Pruneri, Valerio (2018-10-29)
    Article
    Accés obert
    We put forward a simple, scalable and robust technique for generating periodically structured light beams with intensity patterns, e.g. of the form cos2n(kxx) cos2m(kyy), where kx and ky are real numbers that can be tailored ...
  • Inhibition of tunneling and edge state control in polariton topological insulators 

    Zhang, Yiqi; Kartashov, Yaroslav V.; Zhang, Yanpeng; Torner Sabata, Lluís; Skryabin, Dmitry V. (2018-12-01)
    Article
    Accés obert
    We address the inhibition of tunneling in polariton condensates confined in a potential landscape created by a honeycomb array of microcavity pillars in the presence of spin- orbit coupling and Zeeman splitting in the ...
  • Clusters of cavity solitons bounded by conical radiation 

    Milián, Carles; Kartashov, Yaroslav V.; Skryabin, Dmitry V.; Torner Sabata, Lluís (American Institute of Physics (AIP), 2018-09-06)
    Article
    Accés obert
    We introduce a new class of self-sustained states, which may exist as single solitons or form multisoliton clusters, in driven passive cylindrical microresonators. Remarkably, such states are stabilized by the radiation ...
  • Three-dimensional droplets of swirling superfluids 

    Kartashov, Yaroslav V.; Malomed, Boris A.; Tarruell, Leticia; Torner Sabata, Lluís (American Physical Society (APS), 2018-07-12)
    Article
    Accés obert
    A new method for the creation of 3D solitary topological modes, corresponding to vortical droplets of a two-component dilute superfluid, is presented. We use the recently introduced system of nonlinearly coupled Gross-Pitaevskii ...
  • Complex light-assisted optical metrology techniques 

    Rosales Guzmán, Carmelo; Belmonte Molina, Aniceto; Pérez Torres, Juan (International Society for Photo-Optical Instrumentation Engineers (SPIE), 2018)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    The on-demand tailoring of the properties of light, such as phase, polarization or spatial shape, has completely changed the landscape of photonic-based applications. In this way, complex light fields have become an ...
  • Space QUEST mission proposal: experimentally testing decoherence due to gravity 

    Joshi, Siddarth Koduru; Pienaar, Jacques; Ralph, Timothy C.; Pérez Torres, Juan (2018-06-12)
    Article
    Accés obert
    Models of quantum systems on curved space-times lack sufficient experimental verification. Some speculative theories suggest that quantum correlations, such as entanglement, may exhibit different behavior to purely classical ...
  • Optical sectioning in induced coherence tomography with frequency-entangled photons 

    Valles Marin, Adam; Jimenez Machado, Gerard; Salazar Serrano, Luis Jose; Pérez Torres, Juan (American Physical Society, 2018-02-14)
    Article
    Accés obert
    We demonstrate a different scheme to perform optical sectioning of a sample based on the concept of induced coherence [Zou et al., Phys. Rev. Lett. 67, 318 (1991)]. This can be viewed as a different type of optical coherence ...
  • Multicolor solitons 

    Torner Sabata, Lluís; Stegeman, George (2001-06)
    Article

  • Cavity solitons in a microring dimer with gain and loss 

    Milián, Carles; Kartashov, Yaroslav V.; Skryabin, Dmitry V.; Torner Sabata, Lluís (2018-02-20)
    Article
    Accés restringit per política de l'editorial
    We address a pair of vertically coupled microring resonators with gain and loss pumped by a single-frequency field. Coupling between microrings results in a twofold splitting of the single microring resonance that increases ...
  • Lieb polariton topological insulators 

    Li, Chunyan; Ye, Fangwei; Chen, Xianfeng; Kartashov, Yaroslav V.; Ferrando, Albert; Torner Sabata, Lluís; Skryabin, Dmitry V. (American Physical Society, 2018-02-12)
    Article
    Accés obert
    We predict that the interplay between the spin-orbit coupling, stemming from the transverse electric–transverse magnetic energy splitting, and the Zeeman effect in semiconductor microcavities supporting exciton-polariton ...
  • Bound states in the continuum in a two-dimensional PT - symmetric system 

    Kartashov, Yaroslav V.; Milian, Carles; Konotop, Vladimir V; Torner Sabata, Lluís (2018-02-01)
    Article
    Accés restringit per política de l'editorial
    We address a 2D parity-time (¿¿)-symmetric structure built as a chain of waveguides, where all waveguides except for the central one are conservative, while the central one is divided into two halves with gain and losses. ...
  • STED imaging performance estimation by means of Fourier transform analysis 

    Merino, David; Mallabiabarrena, Arrate; Andilla, Jordi; Artigas García, David; Zimmermann, Timo; Loza Alvarez, Pablo (2017-05-01)
    Article
    Accés obert
    Due to relatively high powers used in STED, biological samples may be affected by the illumination in the process of image acquisition. Similarly, the performance of the system may be limited by the sample itself. Optimization ...
