摘要: We have used femtosecond optical spectroscopy to observe directly the vacuum Rabi oscillations associated with coupled exciton-photon mode splitting in a semiconductor quantum microcavity. When microcavity is impulsively excited by coherent short pulse, time-resolved emission from cavity shows beats corresponding oscillation between and exciton modes, decay approximately twice lifetime. Interferometric pump-probe measurements clearly show evolution of polarization.
