FIG. 1.

(Color online) Photoluminescence spectra of a strongly coupled dot-cavity system as a function of bias voltage (false-color plot) for (a) T = 23 K and (b) T = 52 K. (c) Extracted, normalized peak area of the two polariton lines for different temperatures as a function of detuning between exciton and cavity mode.

Image of FIG. 2.
FIG. 2.

(Color online) (a) Photoluminescence spectrum of a QD-cavity system with the cavity mode (marked in blue) detuned to meV lower energy than the single exciton transition (marked in red). (b) Cross-correlation histogram between the cavity mode and the single exciton. Here, corresponds to detection of a photon from the single exciton upon detection of a photon from the cavity mode.

Image of FIG. 3.
FIG. 3.

(Color online) (a) Power dependent photoluminescence spectra recorded from a QD-cavity system with the cavity mode at lower energy than the QD s-shell. The excitation level increases from bottom to top. (b) Integrated photoluminescence intensity from the cavity mode (blue stars), a selected single exciton transition from the s-shell (red triangles), and a selected p-shell multi-exciton transition (black squares).

Image of FIG. 4.
FIG. 4.

(Color online) (a) False color contour plot of the time-resolved photoluminescence intensity of a QD-cavity system as a function of emission wavelength (Ref. 20). (b) PL spectra at different time delays after the laser pulse, each integrated over ns. (c) Extracted, normalized photoluminescence intensity from the cavity mode (blue stars), the single exciton (red triangles), and a p-shell transition (black squares) as a function of time delay after the laser pulse. The IRF is plotted as gray solid line. (d) Schematic energy-level diagram () of a neutral quantum dot (drawn after Ref. 12).
