Suppression of the bottleneck in semiconductor microcavities
The relaxation kinetics of cavity polaritons by scattering with thermal acoustic phonons is studied within the rate equation approximation. Numerical results show that a suppression of the bottleneck of lower polariton states occurs at high polariton densities. We have found that the long decay time of the photon-like polaritons, the thin width of the embedded quantum wells and the small value of exciton-cavity detuning are favorable for the suppression of the bottleneck.
