Abstract
The demonstrate that the optical orientation of excitons can be cohere ntly controlled and directly observed in a resonant time-resolved phot oluminescence experiment. The optical dephasing: time of excitons, the ir longitudinal and transverse spin relaxation times, and their radiat ive lifetime, are measured with strictly the same experimental conditi ons. This technique, which relies on the linear response of the crysta l, is used to investigate the spin-dependent exciton-exciton interacti ons.
