Abstract
A Fabry-Perot optical device, including: a large-diameter elongated optical waveguide having a core and having an air gap region disposed along the longitudinal axis of the waveguide, and with the air gap region enclosed by end faces substantially perpendicular to the longitudinal axis of the waveguide, the waveguide also having a cavity delimited on at least one side by an endface of the air gap, wherein the endface is at least partially reflective. From another perspective, the invention provides an apparatus including: a force-applying assembly, responsive to a control signal containing information about a selected resonated wavelength or a selected filtered wavelength derived from an optical signal, for providing a force; and a Fabry-Perot optical structure, responsive to the force, and further responsive to the optical signal, for providing a Fabry-Perot optical structure signal either with the selected resonated wavelength or without the selected filtered wavelength.
