Abstract

We present investigations on triggered single-photon emission and two-color photon cascades from single quantum dots (QDs) and/or single QDs embedded in microcavities. For the photoluminescence intensity of QDs in pillar microcavities a strong enhancement is revealed in comparison to QDs in bulk semiconductors, thus reflecting an efficient coupling of the emission to the cavity mode. In particular, the capability of efficient triggered single-photon generation from such devices is demonstrated by photon statistics measurements. From investigations on bare QDs without a surrounding cavity structure, we also demonstrate the selective addressing of neutral or charged carrier configurations in individual QDs by variable excitation energy. Direct evidence is found for the temporally-correlated decay of a charged biexciton through an excited trionic QD state.
