A cw-244-nm-Ar(+) laser was used to fabricate Bragg gratings in pristine and H(2)-loaded Bi-Al-SiO(2) optical fibers with index changes as high as 3.6 × 10(-4) and 19.3 × 10(-4), respectively. For comparison, fiber Bragg gratings in pristine and H(2)-loaded SMF-28e showed index changes of 13.6 × 10(-4) and 63.3 × 10(-4). Continuous isochronal thermal annealing revealed higher thermal stability for the H(2)-loaded Bi-Al-SiO(2) fiber compared to the pristine one. The SMF-28e fibers, with and without hydrogen, were more stable than the Bi-Al-SiO(2) fibers.
