Photon lasing inGaAsmicrocavity: Similarities with a polariton condensate
Open accessAbstract
We study experimentally the lasing regime of a $\mathrm{GaAs}$ based microcavity sample under strong optical pumping. The very same sample exhibits the strong coupling regime at low excitation power with a Rabi splitting as large as $15\phantom{\rule{0.3em}{0ex}}\mathrm{meV}$. We show that some features which may be considered as experimental evidence of polariton Bose-Einstein condensation are also observed in the weak coupling regime when the cavity is behaving as a regular photon laser. In particular, the emission pattern in the lasing regime displays a sharp peak near the energy minimum followed by a Boltzmann distribution at higher energies.

Early works assessed thermality in terms of the momentum distribution approaching or not a Bose-Einstein distribution at a well-defined temperature and chemical potential, while recent works have highlighted the need to establish thermalization in terms of rigorous fluctuation-dissipation relations and frequency-dependent observables.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
