Spectroscopic properties of Er3+-doped tellurite glass for 1.55μm optical amplifier

Thermal and optical properties of Er3+-doped oxyfluorotellurite glasses

“…The larger value of DT gives a larger working range during operations for fiber drawing. If DT4100 1C, the glass can be considered as a glass with relatively good thermal ability [5]. The DT values for the present glasses ranges from 135 to 173 1C, which are much larger than 128 1C (T g ¼ 304 1C and T x ¼ 432 1C) reported for TZN (75TeO 2 -20ZnO-5Na 2 O) glass.…”

Effect of bismuth oxide introduction on spectroscopic properties of Er3+/Yb3+ co-doped aluminophosphate glasses

“…Great attentions have been focused on the spectroscopic properties of Er 3+ /Yb 3+ co-doped glassy matrix including phosphate, borate fluoride, and tellurite glasses [1][2][3]. Phosphate glass is an excellent material for amplifier due to its high stimulated emission cross-section, ion exchangeability, high gain coefficient, low upconversion emission and low probability of energy back transfer from Er 3+ to Yb 3+ .…”

Effect of optical basicity on broadband infrared fluorescence in erbium-doped germanate glasses

“…That is, with the increasing of the optical basicity, the refractive index is increased. Meanwhile, based on Judd-Ofelt theory, the radiative lifetime is decreased, when the refractive index is improved [20]. Therefore, with the increasing of optical basicity, the radiative lifetime at the 1.55 m emission is decreased.…”
