In this paper, we compare photosensitivity, refractive-index modulation depth, spectral bandwidth, and excess loss through the inscription of fiber Bragg gratings in unloaded and hydrogen-loaded fibers with low- or high-germanium concentration and boron co-doping. Gratings in hydrogenated boron co-doped fibers possess the highest reflectivity, but with wider bandwidth and strong excess loss. © 2004 Wiley Periodicals, Inc.
