ABSTRACT:
An in-line, spectrally-selective fiber Fabry-Perot transmission filter includes an optical fiber piece having a broad-band mirror and a narrow-band Bragg grating element formed therein, the mirror and the grating forming a Fabry-Perot resonant cavity therebetween. The filter may be used to form part of a fiber ring laser configuration. The combination of the broad-band mirror and the narrow-band Bragg grating element in an optical fiber piece can also be formed into a spectrally-selective fiber Michelson filter.
