<p>A tunable optical device has a compression-tuned optical structure and a displacement sensor. The compression-tuned optical structure responds to an optical signal, and a displacement sensor signal, for providing a compression-tuned optical structure signal containing information about a change in an optical characteristic of the compression-tuned optical structure, and for providing an excitation caused by a change in a displacement of the compression-tuned optical structure. The displacement sensor responds to the excitation, for providing a displacement sensor signal containing information about the change in the displacement of the compression tuned optical structure. The compression-tuned optical structure is an all-glass compression unit shaped like a dogbone. The displacement sensor is a capacitance sensor affixed to the all-glass compression unit for measuring capacitance between two parallel and opposing plates.</p> |
