Título: | Autocorrelation properties of chaotic delay dynamical systems: A study on semiconductor lasers |
Autor: | Porte, Xavier CSIC ORCID; D'Huys, Otti; Jüngling, Thomas; Brunner, Daniel CSIC ORCID; Soriano, Miguel C. ; Fischer, Ingo CSIC ORCID | Fecha de publicación: | nov-2014 | Editor: | American Physical Society | Citación: | Physical Review - Section E - Statistical Nonlinear and Soft Matter Physics 90(5): 052911 (2014) | Resumen: | © 2014 American Physical Society. We present a detailed experimental characterization of the autocorrelation properties of a delayed feedback semiconductor laser for different dynamical regimes. We show that in many cases the autocorrelation function of laser intensity dynamics can be approximated by the analytically derived autocorrelation function obtained from a linear stochastic model with delay. We extract a set of dynamic parameters from the fit with the analytic solutions and discuss the limits of validity of our approximation. The linear model captures multiple fundamental properties of delay systems, such as the shift and asymmetric broadening of the different delay echoes. Thus, our analysis provides significant additional insight into the relevant physical and dynamical properties of delayed feedback lasers. | Versión del editor: | http://dx.doi.org/10.1103/PhysRevE.90.052911 | URI: | http://hdl.handle.net/10261/115956 | DOI: | 10.1103/PhysRevE.90.052911 | Identificadores: | doi: 10.1103/PhysRevE.90.052911 e-issn: 1550-2376 issn: 1539-3755 |
