Abstract:
A method of filtering optical signals () utilizing an optical fiber (A-D). The method of filtering optical signals () includes the steps () selecting an optical fiber (A-D) coupled to a source of optical signals, () disposing a core () in the bore () of the optical fiber (A-D) formed of a core material (), () selecting a core material () to provide a waveguide within the optical fiber (A-D), () disposing an optical grating (-) in a first optical cladding layer () disposed about the core (), () propagating an optical signal within the optical fiber (A-D) guided substantially within the core (), () modifying a propagation path of selected wavelengths comprising said optical signal with the optical grating (-), and () determining selected wavelengths for which the propagation path is modified by selectively varying an energetic stimulus to the core () thereby tuning the waveguide.
