Abstract :
Summary form only given. We present direct experimental evidence of Rabi oscillation (RO) in individual self-assembled quantum dots (SAQDs) and experimental observation of a new quantum interference (QI) phenomenon. Our detailed theoretical investigations attribute this phenomenon to the coherent dynamics resulting from the interplay between RO and QI. We conduct experiments on an In/sub 0.5/Ga/sub 0.5/As SAQD, which can be considered as a three level system To study the interplay of RO and QI, we perform single dot wavepacket interferometry measurements in the strong excitation regime.
