FIG. 2.

(Color online) (a) PL spectrum of a single QD measured at various characteristic excitation wavelengths measured at at . The wavelengths shown in the figure are the excitation wavelengths. The cavity resonance is located at . (b) Schematic illustration of the conduction band of the QD-PhC nanocavity coupling system. The thick red bar corresponds to the energy level of the cavity resonance.

FIG. 3.

(Color online) (a) PL spectrum of the cavity mode and PLE spectrum of the cavity resonant single QD measured at . The PLE signals were measured at the PL peak of the single QD at , and the horizontal axis corresponds to the excitation wavelength for the PLE spectrum. (b) PL intensity peak values of a resonant single QD measured at various temperatures. The excitation wavelength was fixed at the cavity resonance at .
