摘要
A tunable infrared detector is provided that includes a substrate, a bottom wavelength detector formed over the substrate, a top wavelength detector formed over the first wavelength detector layer, and an interferometer filter formed over the top wavelength detector layer and the bottom wavelength detector layer. The interferometer filter is operatively configured to pass a first wavelength associated with a first portion of a predetermined band and a second wavelength associated with a second portion of the predetermined band to the top wavelength detector. The top wavelength detector is operatively configured to detect each wavelength associated with the first portion of the predetermined band and to transmit each wavelength associated with the second portion of the predetermined band to the bottom wavelength detector. The bottom wavelength detector is operatively configured to detect each wavelength associated with the second portion of the predetermined band.
