Bragg gratings in Ce<sup>3+</sup>-doped fibres written by a single excimer pulse
Gratings with as high as 2.4% reflection efficiency written by a 20-ns single excimer pulse at 248 nm have been demonstrated for the first time to our knowledge in Ce<sup>3+</sup>-doped fibers. The grating strength is shown to increase with Ce<sup>3+</sup> concentration under...
