Applications in optical quantum information technology require a new type of light source able to emit exactly one photon periodically with minimal timing jitter. We investigate the …
Abstract Nondegenerate (two-wavelength) two-photon absorption using coherent optical fields is used to show that there are two different quantum mechanical pathways leading to …
Photoluminescence spectra from single self-assembled InAs quantum dots embedded in an Al 0.6 Ga 0.4 As matrix are reported. The spectra consist of a higher-energy linearly …
A semiconductor quantum dot model accounting for single exciton as well as biexciton states coupled to phonons and laser light is investigated in the limit of strong electronic …

Five stacked layers of InAs quantum dots (QDs) embedded in quaternary InGaAsP are grown on (100) InP substrate to form a laser diode. The QD ensemble has a density of 1.5× …
Abstract Using GaAs/AlGaAs self-assembled quantum dots we study the few-particle dynamics of fully confined systems, which is associated with purely Coulomb interaction and …
We investigate the cascaded emission of photons from low-density InGaAs/GaAs quantum dots grown by metal-organic vapor-phase epitaxy that are intentionally redshifted toward …
