Título: | Noise Spectra of a semiconductor ring laser in the bidirectional regime |
Autor: | Pérez Serrano, Antonio CSIC ORCID; Zambrini, Roberta CSIC ORCID ; Scirè, Alessandro CSIC; Colet, Pere CSIC ORCID | Fecha de publicación: | 30-oct-2009 | Editor: | American Physical Society | Citación: | Physical Review A 80(4): 043843-1/043843-7 (2009) | Resumen: | We analytically investigate the influence of complex backscattering coefficients and pump current on the noise spectra of a two-mode model for semiconductor ring laser in the Langevin formulation. The system features in the bidirectional regime are naturally described in terms of the two mode-intensity sum (I spectrum) and difference (D spectrum). The I spectrum reflects the energy exchange between the total field and the medium and behaves similarly to the relative intensity noise for single-mode semiconductor lasers. The D spectrum represents the energy exchange between the two counterpropagating modes and is shaped by the noisy precursor of a Hopf bifurcation induced by the complex backscattering. | Descripción: | 7 pages, 7 figures.-- PACS number(s): 42.55.Px, 42.60.Mi, 42.65.-k | Versión del editor: | http://dx.doi.org/10.1103/PhysRevA.80.043843 | URI: | http://hdl.handle.net/10261/25512 | DOI: | 10.1103/PhysRevA.80.043843 | ISSN: | 1050-2947 |
