Abstract :
We investigate methods to modulate the photodiode responsivity for high-speed photodetection, i.e., parametric down-conversion. Electrical modulation is preferred over optical modulation and gives near optimum efficiency of ~20%. Applications are near- and mid-infrared spectroscopy methods.
