Resonance fluorescence spectra from semiconductor quantum dots coupled to slow-light photonic crystal waveguides
Kaushik Roy-Choudhury, Nishan Mann, Ross Manson +1
Using a polaron master equation approach we investigate the resonance fluorescence spectra from coherently driven quantum dots (QDs) coupled to an acoustic phonon bath and a photon…
Polaron master equation theory of pulse driven phonon-assisted population inversion and single photon emission from quantum dot excitons
Ross Manson, Kaushik Roy-Choudhury, Stephen Hughes
We introduce an intuitive and semi-analytical polaron master equation approach to model pulse-driven population inversion and emitted single photons from a quantum dot exciton. The…
Cavity-enhanced simultaneous dressing of quantum dot exciton and biexciton states
Fabian Hargart, Markus Müller, Kaushik Roy-Choudhury +6
We demonstrate the simultaneous dressing of both vacuum-to-exciton and exciton-to-biexciton transitions of a single semiconductor quantum dot in a high-Q micropillar cavity, using…
Quantum theory of light emission from quantum dots coupled to structured photonic reservoirs and acoustic phonons
Kaushik Roy-Choudhury, Stephen Hughes
Electron-phonon coupling in semiconductor quantum dots plays a significant role in determining the optical properties of excited excitons, especially the spectral nature of emitted…
