Patent ID: 7759644

Claim:
An infrared detector, comprising: a substrate; a bottom wavelength detector formed over the substrate, the bottom wavelength detector having a top side; a passivation layer formed on the top side of the bottom wavelength detector; a top wavelength detector mounted on the passivation layer so that the top wavelength detector is formed over the bottom wavelength detector layer; and an interferometer filter formed over the top wavelength detector layer and the bottom wavelength detector layer, said interferometer filter comprising: a first mirror having a first plurality of dielectric layers, a second mirror having a second plurality of dielectric layers, and at least two flexible supports disposed between the first mirror and the second mirror such that the first mirror is substantially parallel with and disposed a first predetermined distance over the second mirror; wherein the interferometer filter is configured to be tuned by said flexible supports moving the first mirror from the first predetermined distance to a second predetermined distance over the second mirror in response to at least one of an electrical and mechanical input to said supports; the interferometer filter simultaneously passes a first wavelength associated with a first portion of a predetermined band and a second wavelength associated with a second portion of the same 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, and the bottom wavelength detector is operatively configured to detect each wavelength associated with the second portion of the predetermined band, and the bottom wavelength detector detects the second wavelength in the second portion of the predetermined band approximately simultaneously with the top wavelength detector detecting the first wavelength in the first portion of the same predetermined band.
