MIR-Bose: “Mid- and far-IR optoelectronic devices based on Bose-Einstein condensation” is a FET-Open collaborative project funded by European Commission H2020 program. The MIR-Bose project has kick-started on January 1St, 2017 and will run for 4 years.

The MIR-Bose Project is coordinated by Raffaele Colombelli from the Paris Sud University (France) and mobolises 10 partners listed below:

The Objectives of the Project:

Optoelectronic  devices  typically  operate  in  the  weak  coupling  regime  between  light  and  matter,  for  example  in conventional lasers which rely on population inversion to achieve optical gain. Recently, however, there has been a surge of interest in quantum systems operating instead in the strong coupling regime, when the coupling strength of the light-matter interaction is so strong that new states – cavity polaritons – are created, that are partially light, and partially material excitation. In semiconductors, exciton-polaritons have been the most widely studied type of strongly coupled system. However, recently  a  new  phenomenon  has  been  realized  exploiting  intersubband  transitions.
The  resulting  excitations  are called intersubband polaritons, and they have two remarkable properties: (i) a bosonic character that is maintained up to high carrier densities since they are not restricted by the Mott transition limit; and, (ii) large Rabi splittings. Although the scientific community has explored the basic science of intersubband polaritons, their potential for future and innovative optoelectronic devices has been entirely untapped.

The goal of the MIR-BOSE  project  is to demonstrate  novel intersubband optoelectronic  devices operating in the strong coupling regime between light and matter. Ultimately, we aim at demonstrating an intersubband polariton laser. These new sources have the potential to impact a range of technologies and applications in the mid-IR and THz frequency ranges.
