Study of high temperature stable fiber Bragg gratings fabricated in silica based fiber

The temperature stability of fiber Bragg gratings (FBG) fabricated in SMF-28, all-silica core, and high Ge content fibers is investigated. FBG's fabricated in hydrogen loaded SMF-28 and all-silica core fiber are shown to possess high temperature stability. The magnitude of the Bragg resonance in high Ge content fiber is shown to increase with annealing temperature until, at 1000 °C, the grating slowly erases.
