Paper Abstract

The development in recent years of high-performance, wide-bandwidth HgCdTe photodiodes has led to greatly increased CO2 laser heterodyne system capabilities in the GHz region. Near-ideal heterodyne performance has been obtained, not only with single photodiodes, but with quadrantal and 12-element photodiode arrays. Wide-bandwidth photodiode design considerations, fabrication, and heterodyne evaluation techniques and results are presented here, along with a discussion of the factors that limit heterodyne performance and the feasibility of extending the bandwidth into the 5 to 10 GHz region.
