Rabi oscillations and photocurrent in quantum‐dot tunnelling junctions

Boris Fainberg, Abraham Nitzan

Abstract Motivated by the experiments by Zrenner et al. [Nature 418, 612 (2002)], we study the influence of relaxation processes on converting Rabi oscillations in a strongly biased single‐quantum‐dot photodiode into deterministic photocurrents. We show that the behavior of a quantum dot with different tunnel rates for electron and holes is qualitatively different from that with the equal tunnel rates: in the latter case the current shows attenuating oscillations with the Rabi frequency. In contrast, for different electrons and holes tunnelling rates, the frequency of these oscillations diminishes, and they disappear beyond a definite asymmetry threshold. We give an analytical solution of the problem and a numerical example showing a different behaviour of the transferred charge in the small attenuation limit for equal and different tunnel rates for electrons and holes.

Coherent control of single quantum dot exciton embedded in a photodiode

Roman S. Kolodka, A. J. Ramsay, P. W. Fry +6 more

We study the coherent properties of a two-level system based on the ground state neutral exciton of a single InGaAs self-assembled quantum dot (SAQD) embedded in an n-i-Schottky diode. By using a photocurrent technique, we observe Rabi oscillations of the exciton population for pulse-areas of up to 6π. We perform two pulse quantum interference experiments to deduce the decoherence rate.
