H. Poignant et al., EFFICIENCY AND THERMAL-BEHAVIOR OF CERIUM-DOPED FLUOROZIRCONATE GLASS-FIBER BRAGG GRATINGS, Electronics Letters, 30(16), 1994, pp. 1339-1341
1.55mum Bragg gratings have been written in cerium-doped fluorozircona
te glass singlemode fibres through UV illumination at 246nm. Photoindu
ced refractive index changes up to 4 X 10(-4) have been achieved, lead
ing to grating efficiencies close to 100%. Preliminary results on the
thermal behaviour of the gratings and realisation of a tunable laser i
ncluding such a grating are also reported.
