FIG. 3.

(a) Effect of optical power and bias voltage on conversion efficiency, with measured points and modeled curves. (b) Average THz power vs pulse width, showing experimental point and large-signal model.

Power spectra parameterized by bias voltage. Spot frequency measurements are shown by the dark circles. FTIR spectrometer is shown as continuous data at 120 V (topmost trace), 100, 80, 60, 40, and 20 V bias and noise floor (bottom) is below. The spot-frequency data is offset above the FTIR data only for clarity.
