Vacuum radiometry of an infrared nanoantenna-coupled tunnel diode rectenna

Davids, Paul D.; Kadlec, Emil A.; Shank, Joshua S.; Peters, D.W.; Howell, Stephen W.

We examine the vacuum infrared photoresponse of a large-area nanoantenna-coupled tunnel diode rectenna resulting from thermal radiation from a temperature controlled heater. The measured infrared photocurrent is obtained as a function of the source temperature, sample distance and view factor. Far-field radiation power conversion is examined using standard radiometric techniques and correlated with the rectified current response.
