In a collaboration of the Carl von Ossietzky Universität Oldenburg, the Julius-Maximilians-Universität Würzburg, the Friedrich-Schiller-Universität Jena, the Arizona State University, the Westlake University, the Fraunhofer IOF, and the National Institute for Materials Science we have been able demonstrate room temperature polaritonic lasing and also known as polaritonic Bose-Einstein-Condensation.
After a prior demonstration of cryogenic condensation for the group spearheaded by Hangyong Shang, Christian Schneider und Carlos Antón Solanas, we had joined the consortium in summer to provide high grade optics in the quest towards room Temperature operation. Heiko Knopf of the Max Planck School of Photonics thus created monolithic optical cavities with integrated 2D-Materials, which provided sufficent performance to observe room-temperature operation.
This work marks an important milestone towards usable and efficient nanoscale laser-like light sources, which are highly sought after for semiconductor applications and quantum technology.
