The refractive-index modulation of chemical composition gratings in fluorine-germanium-doped silica fibers as a function of thermal treatment during manufacturing has been studied, The final grating strength was found to depend strongly on an intermediate annealing step, with an optimum temperature near 600-700degreesC before development at a fixed temperature of 1000degreesC. Low-temperature treatment, aimed at removing any remaining hydrogen from the fiber, performed at 100degreesC for 20 h before the annealing step, also sigificantly increased the final refractive-index modulation.
