Abstract
We succeeded in recording broad FBG in standard single-mode fibre optic, using saturated hydrogen loading and over-exposure to the UV beam. The reflection spectra of the obtained gratings presents a FWHM line-width between 3 nm and 10 nm, and peak reflectivity in the range from 20 dB to 25 dB. The dispersion of the gratings is also measured and the dispersion coefficient results values about 2.5 ps/nm, at least 10 times smaller than that of conventional broad gratings recorded with chirped refractive index profiles.
