Abstract :
We report on the experimental investigation of combining MM wave mixing with optical heterodyne detection in a quantum well infrared photo detector. The effects of two different non-linear conductances were observed and attributed to the dark conductance and the photo conductance. The bias dependence was found to be similar for each of the conductances.
