1. An apparatus, comprising:
- a tunable resonator including an upper Bragg reflector and a lower Bragg reflector separated by a porous matrix including a sorbent material, said upper Bragg reflector configured to be illuminated by a light source such that light passes through said upper Bragg reflector, then through said porous matrix and exits said lower Bragg reflector to enable said tunable resonator to produce a first spectral optical response from a substance absorbed within said porous matrix; and
a detector positioned on an opposing side of said tunable resonator from said light source configured to detect said light and provide a first absorption signal representing said first spectral optical response.

Abstract
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.

11. A method, comprising:
-
illuminating, by a light source, an upper Bragg reflector of a tunable resonator, said tunable resonator including said upper Bragg reflector and a lower Bragg reflector separated by a porous matrix including a sorbent material, light from said light source passing through said upper Bragg reflector, then through said porous matrix and exits said lower Bragg reflector; producing a first spectral optical response from a substance absorbed within said porous matrix; and providing a first absorption signal representing said first spectral optical response in accordance with detecting said light with a detector positioned on an opposing side of said tunable resonator from said light source. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
