Transparent Ni{sup 2+}-doped MgO-Al{sub 2}O{sub 3}-TiO{sub 2}-SiO{sub 2} glass ceramics were prepared, and the optical properties of Ni{sup 2+}-doped glass ceramics were investigated. Broadband emission centered at 1320 nm was observed by 980 nm excitation. The longer wavelength luminescence compared with Ni{sup 2+}-doped Li{sub 2}O-Ga{sub 2}O{sub 3}-SiO{sub 2} glass ceramics is ascribed to the low crystal field hold by Ni{sup 2+} in MgO-Al{sub 2}O{sub 3}-TiO{sub 2}-SiO{sub 2} glass ceramics. The change in optical signals at the telecommunication bands with or without 980 nm excitation was also measured when the seed beam passes through the bulk gain host.
