Summary:Electromagnetic energy is detected with high efficiency in the spectral range having wavelengths of about 1-2 microns by coupling an absorber layer having high quantum efficiency in the spectral range having wavelengths of about 1-2 microns to an intrinsic semiconducting blocking region of an impurity band semiconducting device included in a solid state photon detector.
