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 ...
