Fabrication/Characterization of Fiber Gratings and Photosensitivity in Ge-Free Bi-Al-Silica Fibers - INVITED

Refractive index changes up to 2.5 × 10-3 were demonstrated in H2-loaded germanium free Bi-Al-doped silica fibers using both ArF excimer and cw-Ar+-244 nm lasers. Tensile stress changes indicate clear contribution of compaction to the total index change.
