Lateral Coupling of InxGa1-xAs/GaAs quantum dots investigated using differential transmission spectroscopy



Kevin L. Silverman, Richard Mirin, Steven T. Cundiff


Coupling between InGaAs/GaAs quantum dots is investigated using differential transmission spectroscopy. Two-color pump-probe techniques are used to spectrally resolve the carrier dynamics revealing carrier transfer between quantum dots at room temperature. The time constant for this process is shown to increase from 35 ps at room temperature to 130 ps at 230 K.
