Abstract
An electromagnetic radiation detector system is disclosed which includes a detector of semiconductor material in the form of a superlattice having a plurality of layers of a first conductivity type spaced by alternate layers of a second conductivity type forming a layered structure having distinct natural energy band gap responsive to a narrow band of electromagnetic wavelengths, but which can be tuned by physical or electromagnetic devices to alter the band of wavelengths to which the detector responds. The system includes electrodes connecting the sensor to an output device.
