Paper Abstract

There are determined distributions of electric field of the light wave, the radiation intensity, the external quantum yield and the carrier concentration in a photosensitive element located in the optical resonanse cavity. The results obtained are used to evaluate the normalized detectivity of the (Hg,Zn)Te photon detector of lO.6piu radiation (PC, PEM and Dember). . It has been found, that the interference effects in a homogeneous with respect to the energy gap and doping, photosensitive element, results in the increase of the detective parameters of the detectors (up to 3 times). It can be obtained the high normalized detectivity * 8 1 1/2 (D >10 cmW Hz ) of uncooled (T300K) and cooled (T200K, D>lO9cmW1Hz1"2) photoresistors, PEM and Dember detectors with the optical cavity.
