El grup de recerca treballa en dues temàtiques principals:
- L'estudi de fenòmens òptics lineals i no lineals en cristalls fotònics i microcavitats.
- L'estudi de la dinàmica espaciotemporal de sistemes no lineals, sobretot de làsers i sistemes òptics en general.

The research group works on two main topics: linear and nonlinear optical phenomena in photonic crystals and microcavities, and the spatiotemporal dynamics of nonlinear systems, in particular lasers and optical systems.

    Article
    Accés obert
    Light localization and intensity enhancement in a woodpile layer-by-layer photonic crystal, whose interlayer distance along the light propagation direction is gradually varied, has been theoretically predicted and ...
  • A study of the air-sea interaction in the South Atlantic Convergence Zone through Granger causality 

    Tirabassi, Giulio; Masoller Alonso, Cristina; Barreiro, Marcelo (Wiley, 2015-10-01)
    Article
    Accés obert
    Air-sea interaction in the region of the South Atlantic Convergence Zone (SACZ) is studied using Granger causality (GC) as a measure of directional coupling. Calculation of the area weighted connectivity indicates that the ...
  • Roadmap on optical rogue waves and extreme events 

    Akhmediev, N; Kibler, Bertrand; Baronio, Fabio; Masoller Alonso, Cristina (Institute of Physics (IOP), 2016-04-26)
    Article
    Accés obert
    The pioneering paper 'Optical rogue waves' by Solli et al (2007 Nature 450 1054) started the new subfield in optics. This work launched a great deal of activity on this novel subject. As a result, the initial concept has ...
  • Self-collimation in PT -symmetric crystals 

    Ahmed Waseem, Waqas Waseem; Herrero Simon, Ramon; Botey Cumella, Muriel; Staliunas, Kestutis (AMER PHYSICAL SOC, 2017-05-10)
    Article
    Accés obert
    We predict the self-collimation phenomena (or equivalently, dynamical localization) in two-dimensional PT-symmetric complex potentials, where the complex modulation is considered in the transverse, longitudinal, or ...
  • Mid-infrared T-shaped photonic crystal waveguide for optical refractive index sensing 

    Turduev, Mirbek; Giden, I.; Giden, Ibrahim H.; Babayigit, Ceren; Bor, Emre; Boztug, Çiçek; Kurt, Hamza; Staliunas, Kestutis (2017-06-01)
    Article
    Accés restringit per política de l'editorial
    In this paper, we propose and design a new type of an integrated optical sensor that performs sensing in a wide wavelength range corresponding to mid-infrared (mid-IR) spectrum. By engineering the structural parameters of ...
  • Suppression of pattern-forming instabilities by genetic optimization

  • Inferring directed climatic interactions with renormalized partial directed coherence and directed partial correlation 

    Tirabassi, Giulio; Sommerlade, Linda; Masoller Alonso, Cristina (Institute of Physics (IOP), 2017-03-22)
    Article
    Accés restringit per política de l'editorial
    Inferring interactions between processes promises deeper insight into mechanisms underlying network phenomena. Renormalised partial directed coherence is a frequency-domain representation of the concept of Granger causality, ...

    Text en actes de congrés
    Accés restringit per política de l'editorial
    We present a novel single-shot cross-correlation scheme based on the measurement of the transverse second harmonic generation (TSHG) in crystals with randomly distributed nonlinear ferroelectric domains. We implement it ...
