(a) TPPL confocal image of the QD sample obtained before closed-loop optimization with 50 μW excitation power. Isolated bright spots, corresponding to TPPL emitted by individual QDs, are clearly resolved. (b) Second order intensity correlation functions corresponding to QD1 and QD2 in a show photon antibunching. The non-classical characteristics of the photon statistics confirm the individual character of QD1 and QD2. (c) Closed-loop optimization of the TPPL signal emitted from the specific single QDs indicated in a. In the case of QD3, we report two different optimization traces to show reproducibility under different conditions.
