Photon statistical measurements on a semiconductor microlaser, obtained using single-photon counting techniques, show that a newly discovered spontaneous pulsed emission regime possesses superthermal statistical properties. The observed spike dynamics, typical of small-scale devices, is at the origin of an unexpected discordance between the probability density function and its representation in terms of the first moments, a discordance so far unnoticed in all devices. The impact of this new dynamics is potentially large, since coincidence techniques are presently the sole capable of characterizing light emitted by nanolasers.

  1. Probing the Ginzburg-Landau Potential for Lasers Using Higher-order Photon Correlations

    cond-mat.mes-hall 2019-08 conditional novelty 6.0 of 10

    For low-beta lasers, the Ginzburg-Landau description of photon statistics remains valid down to photon lifetime equal to carrier lifetime, with relaxation oscillations marking the breakdown.

  2. Photon statistics and dynamics of nanolasers subject to intensity feedback

    physics.optics 2019-08 conditional novelty 5.0 of 10

    For a β=0.1 nanolaser, intensity feedback shifts the lasing transition to lower pump values, narrows it, and produces irregular spiking, with g(2) correlations tracking the dynamics.
