Colloidal-quantum-dot nanolaser oscillating at a bound-state-in-the-continuum with planar surface topography for a high Q-factor [PDF]

open access: yesNanophotonics
Solution-based optical gain materials offer a cost-effective path to coherent light sources. Further, bound states in the continuum (BICs) have garnered great interest owing to their diverging quality (Q) factors.

Metallic coaxial nanolasers [PDF]

open access: yesAdvances in Physics: X, 2016
The last two decades have witnessed tremendous advancements in the area of nanophotonics and plasmonics. Undoubtedly, the introduction of metallic structures has opened a path towards light confinement and manipulation at the subwavelength scale { a regime that was previously thought to be out of reach in optics.

Les nanolasers [PDF]

open access: yesReflets 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

open access: yesNew 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
