Patent ID: 8120782

Claim:
A method of producing a device that includes a tunable optical cavity structure with a light-transmissive region between first and second inward light-reflection components; the method comprising: fabricating the optical cavity structure so that it includes an analyte region that can contain analyte within the light-transmissive region and a tuning structure; the tuning structure responding to tuning signals by moving the first and second inward light-reflection components to any of a set of positions relative to each other; presence of the analyte in the analyte region affecting the optical cavity's output light; the act of fabricating the optical cavity structure including: wherein fabricating the tuning structure includes: forming one or more deformable components connected so that deformation of at least one of the deformable components causes the first and second inward light-reflective components to move within the set of positions; at least one of the deformable components bounding in part the analyte region; and coupling at least one signal-responsive component to receive the tuning signals and, in response, cause deformation of at least one of the deformable components that bound in part the analyte region.
