Abstract

This paper presents experimental results describing the dc and CO2 laser heterodyne characteristics of single element and four element n+-n--p Hg0.8Cd0.2Te photodiode arrays. These diodes exhibited wide bandwidths (~2.0 GHz) and fairly good effective heterodyne quantum efficiencies (~13-30% at 2.0 GHz). Typical noise equivalent powers of approximately 1.44 x 10-20w/Hz to 6.23 x 10-20w/Hz have been measured at 2.0 GHz.
