## Abstract A Fabry‐Perot filter is realized by inscribing two identical 1 mm uniform Bragg gratings separated by 7.7 mm space in the hydrogen‐loaded photosensitive optical fiber. It is then incorporated with a tunable chirped fiber Bragg grating into a fiber ring cavity. Fourteen single‐wavelength
