Abstrakt: Er-doped tellurite glass (TeO-ZnO-NaO) prepared using the conventional melt-quenching method is modified by introducing the SiO, and its effects on the thermal stability of glass host and the 1.53 μm band spectroscopic properties of Er are investigated by measuring the absorption spectra, 1.53 μm band fluorescence spectra, Raman spectra and differential scanning calorimeter (DSC) curves. It is found that for Er-doped tellurite glass, besides improving its thermal stability, introducing SiO is helpful for the further improvement of the fluorescence full width at half maximum (FWHM) and bandwidth quality factor. The results indicate that the prepared Er-doped tellurite glass containing an appropriate amount of SiO has good prospect as a candidate of gain medium applied for 1.53 μm broadband amplifier.
