FIG. 1.

(Color online) spectrum of the modified cavity around its fundamental mode under pulsed excitation (, , and ). A Lorentzian fit (gray area) of the mode yields a quality factor . A doublet excitonic line labeled QD1 is visible at lower energies. The inset shows a scanning electron microscopy image of this cavity.

FIG. 2.

(Color online) (a) spectra (, ) showing a QD and the redshift of the mode due to air molecules being cold trapped on the surface of the sample. As the mode approaches QD1, we observe a marked increase in its emission intensity. (b) Integrated intensity of QD1 as a function of the detuning with respect to the mode energy.

Image of FIG. 3.
FIG. 3.

(Color online) Time resolved dynamics of QD1 off resonance (empty circles), of ensemble QDs outside the PhC region (diamonds), of the background emission coupled to the mode off resonance with QD1 (empty squares), and of QD1 on resonance with the cavity mode under (filled circles) and (filled triangles) excitation powers and a repetition rate.
