FSR-tunable Fabry-Perot filter with superimposed chirped fiber Bragg gratings

Tuning of the free-spectral range (FSR) of an optical fiber Fabry-Pe/spl acute/rot filter (FPF), which is formed by a superimposed chirped fiber Bragg grating, is realized by using a cantilever beam-based chirp tuning method. The tuning principle is described and, as an example, an FPF with a contin...

Description
Summary:Tuning of the free-spectral range (FSR) of an optical fiber Fabry-Pe/spl acute/rot filter (FPF), which is formed by a superimposed chirped fiber Bragg grating, is realized by using a cantilever beam-based chirp tuning method. The tuning principle is described and, as an example, an FPF with a continuously tunable FSR of 0.3-0.6 nm is demonstrated.
