I agree Rainer. That is a significant find by Guernsey!
I can't help but to think about the sensitivity of POETs GaAs resonant cavity detector and its usefulness in an IR focal plane array. I always believed that it was a very significant indicator of how much gain is built into Geoff Taylor’s design. I recall talking to Sam Peralta about the military applications so it really did not make sense to me when it dropped out of public view.
