Abstract
A dual-band infrared detector is provided. The dual-band infrared detector includes a first absorption layer sensitive to radiation in only a short wavelength infrared spectral band, a plurality of barrier layers coupled to the first absorption layer, and a second absorption layer coupled to the plurality of barrier layers opposite the first absorption layer. The second absorption layer is sensitive to radiation in only a medium wavelength infrared spectral band, and the first and second absorption layers are formed from materials having a lattice parameter mismatch less than a predetermined threshold.
