Apparatus for detecting a substance and method of operating the same Patent uri icon


  • An apparatus configured to detect a substance, and method of operating and forming the same. In one embodiment, the apparatus includes a tunable resonator including an upper Bragg reflector and a lower Bragg reflector separated by a porous matrix. The tunable resonator is configured to be illuminated by a light source and produce a first spectral optical response from a substance absorbed within the porous matrix. The apparatus also includes a detector positioned proximate the tunable resonator configured to provide a first absorption signal representing the first spectral optical response.
