摘要：

We report on the dynamics of resonantly excited lower branch polariton states in a semiconductor quantum microcavity. We show that both the spin orientation and the density of polaritons can be coherently manipulated. The measurements of the optical dephasing Lime T-2 and the decay time T-1 of the radiant states asa function of the cavity detuning and the lattice temperature give further insights into the relaxation mechanisms of cavity polaritons.
