We are interested in semiconductor laser (SL) dynamics, namely its multimode stability. To that aim a microcanonical (MC) model was built and is very effective, but highly time-consuming to simulate [1]. We then question about the relevance of this statistical ensemble. The model represents a SL by a Markov chain. It is composed of photon...

Nous présentons un modèle traitant du passage au seuil des nanolasers grâcè a une chaˆınechaˆıne de Markov simulée par Monte-Carlo. La quantification des variables traitées dans le modèle permet de mettre enévidenceen´enévidence les allumages et extinctions autour du seuil laser. La coexistence d'un régime pulsé avec un régime continu bruité...

A Markov model of semiconductor nanolaser is constructed in order to describe finely the effects of quantum fluctuations in the dynamics of the laser, in particular by considering the transition to lasing. Nanolasers are expected to contain only a small number of emitters, whose semiconductor bands are simulated using true carrier energy...

We theoretically compute the coupling constant C between two emission modes of an extended cavity laser with a multiple quantum-well active layer. We use an optimized Monte Carlo model based on the Markov chain that describes the elementary events of carriers and photons over time. This model allows us to evaluate the influence on C of the...
