Photovoltaic detectors cutoff wavelength

This graph summarizes the wavelength response of some semiconductors used as detectors for infrared radiation. The quantity D (X) is the signal to noise ratio for an incident radiant power density of 1 W/cm and a bandwidth of 1 Hz (60° field of view). The Ge, InAs, and InSb detectors are photovoltaics, while the HgCdTe series are photoconductive devices. The cutoff wavelength of the latter can be varied by adjusting the relative amounts of Hg, Cd,... [Pg.1713]

Fig. 2.15. Photon noise limited Df at peak wavelength (assumed to be cutoff wavelength), for a photovoltaic detector for selected background temperatures Tg. Values for a cooled photoconductive detector are 0.71 times those shown. (Assumes 27t steradian field of view and >/ = 1) (after Jacobs and Sargent [2.160])... Fig. 2.15.
