Bose-Einstein condensation of photons in a vertical-cavity surface-emitting laser

M. Pieczarka, M. Gębski, et al.

This groundbreaking research reveals the phenomenon of Bose-Einstein condensation (BEC) of photons in a vertical-cavity surface-emitting laser (VCSEL). Observations showcased a BEC at critical phase-space density, while demonstrating insights into the superfluid physics of interacting photons, thanks to the work of Maciej Pieczarka, Marcin Gębski, Aleksandra N. Piasecka, James A. Lott, Axel Pelster, Michał Wasiak, and Tomasz Czyszanowski.
