Paper Abstract

There are many infrared systems which require detectors with controlled spectral responsivities. One of the examples is laser warning device. The spectral response of detectors for this particular application should cover a wide spectral range from about 0.6 micrometer to 11 micrometer. Thermal detectors are unselective, but they suffer from poor speed of response. In contrast, the photon detectors exhibit much better speed of response and sensitivity. The spectral responsivities of conventional photodetectors are close to that of the ideal photon counter with a given cut-off wavelength. It means that responsivities at short wavelength are highly reduced. Here we report MPC IR photodetector, which covers the required spectral band of 0.6 - 11 micrometers, exhibiting increased at short wavelengths. Calculation results of range of device which applies these detectors also are presented.
