Abstract :
Summary form only given. Optical Rabi oscillations are the most essential physics that coherent optical control of the quantum states relies on. Observation of the exciton population flopping thus can be a first step to the coherent control. In this contribution, we report the Rabi oscillation of an isolated excitonic two-level system in a disk-shaped In/sub x/Ga/sub 1-x/As quantum dot. Control of population and phase of single-dot exciton is demonstrated.
