Image of FIG. 1.
FIG. 1.

Arrays of site-controlled pyramids with a base side, overgrown with a nominally thick GaAs layer. (a) Top-view tapping mode AFM image of a single pyramid. The dashed lines indicate the initial boundaries of the pyramid. (b) Schematic illustration of the overgrown pyramid. (c) Top-view phase mode AFM image of a pitch array of overgrown pyramids.

FIG. 2.

(a) Cavity response calculated via 3D FDTD numerical simulations. The horizontal dashed line represents the uncertainty on the wavelength of the cavity mode. The origin of this uncertainty lies in the experimental error associated with the measured values of and . (b) Schematic illustration of membrane cavity showing the pyramidal QD at its center. The calculated intensity electric field distribution of the confined mode is superposed. (c) AFM image of a pyramidal QD integrated in the PhC.

Image of FIG. 3.
FIG. 3.

(a) Micro-PL spectra of the integrated QD-cavity structure acquired at several temperatures. (b) Temperature dependence of the wavelength of the “free” QD emission (black filled circles and squares) and of that of the observed cavity mode (red filled diamonds). The continuous lines are guides to the eye.
