Patent ID: 8456620

Claim:
An apparatus for spectroscopically analyzing radiation, comprising: a plurality of resonant absorbers disposed on a substrate; and a plurality of sensing elements adjacent to the plurality of resonant absorbers, wherein the plurality of resonant absorbers comprise metamaterials, wherein the plurality of resonant absorbers comprise a plurality of absorptive regions including a first absorptive region and a second absorptive region, the first absorptive region including a plurality of first resonant absorbers of the plurality of resonant absorbers, the plurality of first resonant absorbers each having substantially a first size and the first absorptive region having a first absorptive response including a first peak absorptive response at a first wavelength, and the second absorptive region including a plurality of second resonant absorbers of the plurality of resonant absorbers, the plurality of second resonant absorbers each having substantially a second size different than the first size, and the second absorptive region having a second absorptive response including a second peak absorptive response at a second wavelength different than the first wavelength, wherein the first wavelength substantially corresponds to a wavelength of either visible or infrared radiation and the second wavelength substantially corresponds to a wavelength of either visible or infrared radiation, and wherein the plurality of sensing elements comprise a first sensing element and a second sensing element, the first sensing element being thermally coupled to substantially only the first absorptive region, and the second sensing element being thermally coupled to substantially only the second absorptive region.
