Paper Abstract

We report on the dynamics of resonantly excited polariton states in semiconductor quantum microcavities. We show that the spin orientation of cavity polaritons can be coherently manipulated. The measurements of the optical dephasing time and the decay time of the radiant states as a function of the cavity detuning and the lattice temperature give further insights into the relaxation mechanisms of cavity polaritons. The influence of the polariton lifetime on the optical dephasing time is demonstrated. For zero detuning, a quenching of the polariton-acoustic phonon scattering is evidenced at low temperature.
