Abstract:
An optical resonator sensor, comprising:A. a substrate; B. an optical waveguide, comprising: (a) a multi-layer dielectric stack disposed on said substrate, said dielectric stack including alternating high and low refractive index dielectric layers; (b) a waveguide core disposed on said dielectric stack and having an input end and an output end, said waveguide core being adapted for transmitting light incident on said input end to said output end; C. an optical microcavity disposed along a sensing axis; wherein said optical microcavity is constructed and arranged so as to optically interact with said light incident on said input end of said optical waveguide core; and D. a flexure having a first end coupled to said substrate and a second end arranged to interact with said optical microcavity, said flexure being responsive to an input to cause a change in the coupling geometry between said microcavity and said optical waveguide.
