Quantum degeneracy of polaritons in a GaAs based Microcavity

Polariton quantum degeneracy is obtained in a GaAs Microcavity by pulsed resonant excitation of the excitonic, reservoir. Time resolved emission is monitored in this stimulated regime along the polariton branch.

Analyzing the polariton population distribution for different time delays, we conclude that polariton thermalization is not achieved and that the dynamics is governed by the scattering kinetics from the reservoir into the polariton trap.
