Thanks to two coupled nanolasers, physicists were able to generate an out-of-equilibrium system emitting multi-photon bursts, known as "super-thermal" light. This approach is not restricted to lasers but it can be extended to other nanoscale systems.
The nascent study of out-of-equilibrium statistics in nanoscale, low photon number systems is particularly promising. This work, published in the journal Physical Review X by a team of physicists from the Centre de Nanosciences et de Nanotechnologies - C2N (CNRS / Université Paris-Sud / Université Paris-Saclay) was produced in collaboration with the University of the Balearic Islands.
