Abstract:Nanolasers operating at low power levels have intrinsic quantum noise, strongly affecting intensity fluctuations and laser coherence. In this talk, I’ll show how we can use stochastic simulation methods, originally developed for modeling chemical reactions, to study the interaction of photons and electrons in nanolasers. Starting from full quantum mechanical master equations, I derive a Markov-chain model, which can be sampled using Gillespie's First Reaction Method to accurately predict many properties of the nanolaser, including the intensity noise and emission spectrum. This approach offers a way to model and study the mesoscopic regime of nanolasers, with several tens or hundreds of emitters, where full quantum mechanical treatments are impossible and semiclassical rate equations with Langevin noise are <a href="http://invalid.Co-sponsored" target="_blank" title="invalid.Co-sponsored">invalid.Co-sponsored by: Prof. Nicolas QuesadaSpeaker(s): Matias Bundgaard-NielsenJ.
