Observation of the transition from lasing driven by a bosonic to a fermionic reservoir in a GaAs quantum well microcavity

S. Brodbeck, H. Suchomel, M. Amthor +4

We show that, by monitoring the free carrier reservoir in a GaAs-based quantum well microcavity under nonresonant pulsed optical pumping, lasing supported by a fermionic reservoir…
