FIG. 3.

Voltage-resolved photoluminescence plots for the holes described in Fig. 2. Originally, the cavity mode is nondegenerate (splitting around ) and QD-3 is around 0.5 meV detuned to the blue-side of the cavity mode. Burning 6 holes reduces the splitting to about and QD-3 is about 0.1 meV detuned. Applying isotropic strain, by burning pair of holes along orthogonal direction, the dot can be brought into resonance with the cavity mode, without destroying the mode degeneracy (see plot for 11 holes, bottom right). See Fig. 2 for the position of the holes.
