    • Lag alternance in unidirectional coupled semiconductor lasers 

      Tiana Alsina, Jordi; García López, J.H.; Torrent Serra, Maria del Carmen; García Ojalvo, Jordi (2009)
      Text en actes de congrés
      Accés obert
    • Multidimensional subwavelength position sensing using a semiconductor laser with optical feedback 

      Cohen, Seth; Aragoneses Aguado, Andrés; Rontani, Damien; Torrent Serra, Maria del Carmen; Masoller Alonso, Cristina; Gauthier, Daniel (2013-11-01)
      Article
      Accés obert
      We demonstrate experimentally how to harness quasi-periodic dynamics in a semiconductor laser with dual optical feedback for measuring subwavelength changes in each arm of the cavity simultaneously. We exploit the ...
    • Numerical and experimental study of the effects of noise on the permutation entropy 

      Quintero Quiroz, Carlos Alberto; Pigolotti, Simone; Torrent Serra, Maria del Carmen; Masoller Alonso, Cristina (2015-09-02)
      Article
      Accés obert
      We analyze the effects of noise on the permutation entropy of dynamical systems. We take as numerical examples the logistic map and the Rössler system. Upon varying the noise strength we find a transition from an ...
    • Processing distributed inputs in coupled excitable lasers 

      Martínez González, Cristina; Martín Buldú, Javier; Torrent Serra, Maria del Carmen; García Ojalvo, Jordi (2007-11)
      Article
      Accés obert
      In many instances, networks of dynamical elements are subject to distributed input signals that enter the network through different nodes. In these cases, processing of the input signals may be mediated by coupling, in ...
    • Quantifying the degree of locking in weakly forced stochastic systems 

      Tiana Alsina, Jordi; Quintero Quiroz, Carlos Alberto; Torrent Serra, Maria del Carmen; Masoller Alonso, Cristina (American Institute of Physics (AIP), 2019-02-12)
      Article
      Accés obert
      Controlling an stochastic nonlinear system with a small amplitude signal is a fundamental problem with many practical applications. Quantifying locking is challenging, and current methods, such as spectral or correlation ...
    • Quantitative identification of dynamical transitions in a semiconductor laser with optical feedback 

      Quintero Quiroz, Carlos Alberto; Tiana Alsina, Jordi; Roma, Josep; Torrent Serra, Maria del Carmen; Masoller Alonso, Cristina (Macmillan Publishers, 2016-11-18)
      Article
      Accés obert
      Identifying transitions to complex dynamical regimes is a fundamental open problem with many practical applications. Semi- conductor lasers with optical feedback are excellent testbeds for studying such transitions, as ...
    • State space reconstruction of spatially extended systems and of time delayed systems from the time series of a scalar variable 

      Quintero Quiroz, Carlos Alberto; Torrent Serra, Maria del Carmen; Masoller Alonso, Cristina (Institute of Physics (IOP), 2018-07-11)
      Article
      Accés obert
      The space-time representation of high-dimensional dynamical systems that have a well defined characteristic time scale has proven to be very useful to deepen the understanding of such systems and to uncover hidden features ...
    • Synchronization via clustering in a small delay-coupled laser network 

      Martínez González, Cristina; Masoller Alonso, Cristina; Torrent Serra, Maria del Carmen; García Ojalvo, Jordi (2007-09)
      Article
      Accés restringit per política de l'editorial
    • 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 ...
    • Unveiling the complex organization of recurrent patterns in spiking dynamical systems 

      Aragoneses Aguado, Andrés; Perrone, Sandro; Sorrentino Amaral, Taciano; Torrent Serra, Maria del Carmen; Masoller Alonso, Cristina (MACMILLAN PUBLISHERS LIMITED, 2014-04-15)
      Article
      Accés obert
      Complex systems displaying recurrent spike patterns are ubiquitous in nature. Understanding the organization of these patterns is a challenging task. Here we study experimentally the spiking output of a semiconductor laser ...
