Fiber Bragg gratings with enhanced thermal stability

Gilberto Brambilla and Harvey Rutt


Gratings written in tin-doped silica fibers by using a 248 nm excimer laser exhibit extremely high thermal stability. Isothermal measurements up to 1100 K demonstrate significant advantages over conventional fiber gratings. Extrapolations from experimental data indicated that gratings operating at 500 K for ten years will retain more than 99% of the initial strength.
