FIG. 1.

(Color online) Left: SEM image of the two n- and p-contact pads with the proton implant region and photonic crystal devices in between (labeled). Top right: SEM image of one of the photonic crystal devices. The proton implant region is clearly visible as a dark strip through the center of the device. Bottom right: schematic of the layer structure for the proton implant sample.

FIG. 2.

(Color online) Each of the two cavity regions is monitored separately as the voltage is scanned on either the emission cavity or the opposite cavity. (a) The voltage is scanned across the left set of contacts while the emission from the left cavity is monitored. Clear tuning of quantum dot lines is visible. (b) The voltage is scanned across the right set of contacts while the emission from the left cavity is monitored. No tuning is visible. (c) The voltage is scanned across the left set of contacts while the emission from the right cavity is monitored. No tuning is visible. (d) The voltage is scanned across the right set of contacts while the emission from the right cavity is monitored. Clear tuning of quantum dot lines is visible. Each spectrum in (a)-(d) is normalized to itself so that the maximum intensity remains constant across each scan.

FIG. 3.

(Color online) (a)-(c) Spatial maps of the emission from the left cavity of three different devices at the left cavity resonant wavelength as a function of pump position on the sample. The color scale corresponds to the log of intensity. (a) and (b) are the scans of cavities in which the cavity mode resonant wavelengths are spaced by less than their linewidths. (c) is a scan of a cavity with two cavity mode wavelengths spaced by more than their linewidths.
