Behavioral regimes and long-lived emitter states in mesolasers

Emergence of long-lived emitter states is predicted to occur in a mesolaser driven below self-quenching threshold. Distinct behavioral regimes of the emitters are separated by peaks in photon fluctuations (the Fano factor) in a manner analogous to but fundamentally different from the nonequilibrium phase transition analogy in conventional lasers. The parameter space in which long-lived states emerge in mesolasers containing two or more emitters is identified and shown to be controlled by the strength of coupling to external baths.
