Expérimental et théorique Description
The optical properties of highly doped semiconductor quantum wells are a paradigmatic manifestation of P. Anderson’s “More is different”. Indeed, for high electronic densities, there are no more optical transitions between electronic states and the absorption spectrum of the system shows a unique resonance associated with a collective mode of the system: the quantum plasmon.
In this project, we plan to exploit the superradiant properties of quantum plasmons to create efficient cold sources, operating as mid-infrared light-emitting diodes.
