Query: Superthermal photon bunching in terms of simple probability
  distributions   We analyze the second-order photon autocorrelation function $g^{(2)}$ with
respect to the photon probability distribution and discuss the generic features
of a distribution that result in superthermal photon bunching ($g^{(2)}>2$).
Superthermal photon bunching has been reported for a number of optical
microcavity systems that exhibit processes like superradiance or mode
competition. We show that a superthermal photon number distribution cannot be
constructed from the principle of maximum entropy, if only the intensity and
the second-order autocorrelation are given. However, for bimodal systems an
unbiased superthermal distribution can be constructed from second-order
correlations and the intensities alone. Our findings suggest modeling
superthermal single-mode distributions by a mixture of a thermal and a lasing
like state and thus reveal a generic mechanism in the photon probability
distribution responsible for creating superthermal photon bunching. We relate
our general considerations to a physical system, a (single-emitter) bimodal
laser, and show that its statistics can be approximated and understood within
our proposed model. Furthermore the excellent agreement of the statistics of
the bimodal laser and our model reveal that the bimodal laser is an ideal
source of bunched photons, in the sense that it can generate statistics that
contain no other features but the superthermal bunching.
