FIG. 1.

Output power of ion-irradiated- photomixers coupled to TEM HA vs the frequency difference between the two lasers. The bias voltage was 1.28 V and the total optical power incident was 100 mW. Inset: Schematic of the devices.

FIG. 2.

Output power at 688 GHz as a function of the photocurrent at constant bias voltage of 0.48, 0.68, 0.88, 1.08, 1.18, and 1.28 V. The varied parameter is the optical power incident on the photomixer device.

Image of FIG. 3.
FIG. 3.

Output power at 688 GHz vs voltage at fixed optical power of 50, 60, 70, 80, 90, and 100 mW. Inset: Current under illumination as a function of the bias voltage in ion-irradiated photomixer.

Image of FIG. 4.
FIG. 4.

Normalized output power as function of bias voltage at 890 MHz, 3 GHz, 6 GHz, 10 GHz, and 20 GHz. The curves were normalized by the output power values at 0.6 V for clarity of the figure. Dashed and dot lines show quadratic and quartic dependence of output power on bias voltage.
