摘要：
Bragg gratings made in heavily doped phosphate glass fibers using ultrafast infrared radiation and a phase mask are reported. Refractive indexes > 1.5 x 10(-3) were induced in Er-Yb-doped phosphate fiber in a few seconds of exposure corresponding to reflectivity above 99.99% for a 6-mm-long grating. Annealing test up to 400 degrees C shows good thermal stability of the grating structure.
