Monte Carlo markovian models of a dual-mode semiconductor laser with quantum well (QW) or quantum dot(QD) active regions are proposed. Accounting for carriers and photons as particles that may exchange energy inthe course of time allows an ab initio description of laser dynamics such as the mode competition and intrinsiclaser noise. We used...

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...

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...

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...

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...
