Abstract
Bragg gratings inscription experiments have been performed on fluorozirconate glasses (ZBLA) doped with Ho3+, as well as on fluorozirconate planar waveguides realized by chlorine ion exchange and doped with Ce3+ and Er3+. Both 244 nm and 260 nm light were used. The inscription wasn't possible in any case in the Ce3+ doped planar waveguide. Gratings were written in the Er3+ doped planar waveguide at 260 nm only. In the case of Ho3+ doped fluorozirconate bulk, the inscription was possible at both wavelengths. These results are discussed.
