摘要

OpticalRabi oscillations are coherent population oscillations of a two - level system coupled by an electric dipole transition when driven by a strong nearly resonant optical field. In quantum dot structures, these measurements have typically been performed as a function of the total pulse area function of ohm(0)(t)(dt) where the pulse area varies as a function of Rabi frequency. Here, we report direct detection of the time - resolved coherent transient response of the resonance fluorescence to measure the time evolution of the optical Rabi oscillations in a single charged InAs quantum dot. We extract a decoherence rate consistent with the limit from the excited.
