FIG. 1.

Sketch of the single-photon source with integrated optical fiber A wafer was mounted onto the sample holder (right inset) with fibers attached directly on the top surface by the fiber holder (left inset).

FIG. 2.

(a) Photoluminescence spectra of single quantum dots from different optical fibers in a single fiber bundle. (b) Photoluminescence spectra of a single quantum dot, as a function of excitation power. [In both (a) and (b) spectra are shifted vertically for clarity.]

Image of FIG. 3.
FIG. 3.

(a) Photoluminescence spectrum of a single quantum dot is shown for each of two angular positions of the interference filter; in the lower spectrum the filter has eliminated the contribution from the wetting layer. (b) Second-order correlation function measured (solid squares) and fitted (line) of the PL spectra corresponding to (a) with dark counts. The results of inset are corrected values without dark counts.

Image of FIG. 4.
FIG. 4.

Change in emission wavelength measured over a period is plotted for 27 quantum dots from different optical fibers.
