Résumé :

Semiconductor lasers (SL) have a wide range of applications, but a weak optical feedback destabilizes its normal output. The instabilities generate higher intensity or frequency noise which are undesirable for certain applications. Fourier spectra measurements with numerical studies of rate equations show that these instabilities result from successive bifurcations. In this respect, the bifurcations are analyzed using modern asymptotic techniques, taking advantage of the natural parameters of laser equations. The laser subject to injection and the laser subject to an optical feedback are studied using the rate equations for the complex electrical field E and the carrier number N.
