Plasmon Enhancement Reveals Origin of the Dark States of Photoluminescence Intermittency in Quantum Dots. [PDF]

Nanophotonics
ABSTRACT Dark states of photoluminescence (PL) intermittency in colloidal quantum dots (QDs) interrupt PL emission and significantly reduce emission intensity, severely hindering QD applications. However, the origin of dark states remains ambiguous due to their extremely low intensity, which impedes the development of effective suppression strategies ...

Les nanolasers [PDF]

Reflets de la physique, 2010
Lorsque les dimensions des lasers deviennent submicroniques, la physique qui gouverne leur fonctionnement est modifiee : les effets quantiques sont alors preponderants et le role joue par l’emission spontanee devient tres important, non seulement au passage du seuil, mais aussi en regime d’emission stimulee.

Dissipative Josephson effect in coupled nanolasers

New Journal of Physics, 2021
Josephson effects are commonly studied in quantum systems in which dissipation or noise can be neglected or do not play a crucial role. In contrast, here we discuss a setup where dissipative interactions do amplify a photonic Josephson current, opening a
