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.

  • Predictability of optical rogue waves in optically injected semiconductor lasers 

    Martinez Alvarez, Nuria; Reinoso, Jose A.; Masoller Alonso, Cristina (Optical Society of American (OSA), 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    The predictability of ultra-high pulses emitted by optically injected semiconductor lasers is studied by using symbolic time-series analysis. Pulse patterns that are likely to occur before the rogue wave are identified.
  • Global atmospheric dynamics investigated by using Hilbert frequency analysis 

    Zappala, Dario; Barreiro, Marcelo; Masoller Alonso, Cristina (2016-11-16)
    Article
    Accés obert
    The Hilbert transform is a well-known tool of time series analysis that has been widely used to investigate oscillatory signals that resemble a noisy periodic oscillation, because it allows instantaneous phase and frequency ...
  • Unravelling the community structure of the climate system by using lags and symbolic time-series analysis 

    Tirabassi, Giulio; Masoller Alonso, Cristina (Macmillan Publishers, 2016-07-11)
    Article
    Accés obert
    Many natural systems can be represented by complex networks of dynamical units with modular structure in the form of communities of densely interconnected nodes. Unraveling this community structure from observed data ...
  • Unveiling temporal correlations characteristic to phase transition in the output intensity of a fiber laser 

    Aragoneses, Andrés; Carpi, Laura; Tarasov, N.; Churkin, D.V.; Torrent Serra, Maria del Carmen; Masoller Alonso, Cristina; Turitsyn, S.K. (2016-01-22)
    Article
    Accés obert
    We use advanced statistical tools of time-series analysis to characterize the dynamical complexity of the transition to optical wave turbulence in a fiber laser. Ordinal analysis and the horizontal visibility graph applied ...
  • Formation of high-order acoustic Bessel beams by spiral diffraction gratings 

    Jimenez, Noe; Pico Vila, Rubén; Sánchez Morcillo, Victor José; Romero García, Vicenç; Garcia Raffi, Luis Miguel; Staliunas, Kestutis (2016-11-23)
    Article
    Accés obert
    The formation of high-order Bessel beams by a passive acoustic device consisting of an Archimedes' spiral diffraction grating is theoretically, numerically, and experimentally reported in this paper. These beams are ...
  • Slow light enabled wavelength demultiplexing 

    Hayran, Zeki; Turduev, M.; Botey Cumella, Muriel; Herrero Simon, Ramon; Staliunas, Kestutis; Kurt, H. (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Text en actes de congrés
    Accés obert
    Photonic crystal waveguides supporting band gap guided modes hold great potential to tailor the group velocity of propagating light. We propose and explore different wavelength demultiplexer design approaches that ...
  • Asymmetric light transmission in PT-Symmetric microring resonators 

    Giden, I.; Dadashi, Kh.; Botey Cumella, Muriel; Herrero Simon, Ramon; Staliunas, Kestutis; Kurt, Hamza (2016-03-15)
    Article
    Accés restringit per política de l'editorial
    We propose a new type of add-drop microring resonator made of gain and loss materials. Microring resonators are compact, narrow band, and optical channel dropping filters. In such linear systems, light transmission to ...
  • Quantification of network structural dissimilarities 

    Schieber, Tiabo A.; Carpi, Laura; Díaz Guilera, Albert; Pardalos, Panos M.; Masoller Alonso, Cristina; Ravetti, Martin G. (2017-01-09)
    Article
    Accés obert
    Identifying and quantifying dissimilarities among graphs is a fundamental and challenging problem of practical importance in many fields of science. Current methods of network comparison are limited to extract only partial ...
  • Analysis of noise-induced temporal correlations in neuronal spike sequences 

    Reinoso, Jose A.; Torrent Serra, Maria del Carmen; Masoller Alonso, Cristina (2016-11-01)
    Article
    Accés restringit per política de l'editorial
    We investigate temporal correlations in sequences of noise-induced neuronal spikes, using a symbolic method of time-series analysis. We focus on the sequence of time-intervals between consecutive spikes (inter-spike-intervals, ...
  • Transition between functional regimes in an integrate-and-fire network model of the thalamus 

    Barardi, Alessandro; García Ojalvo, Jordi; Mazzoni, Alberto (2016-09-06)
    Article
    Accés obert
    The thalamus is a key brain element in the processing of sensory information. During the sleep and awake states, this brain area is characterized by the presence of two distinct dynamical regimes: in the sleep state activity ...
