Abstract
B2O3 has been introduced in Er3+-doped tellurite glasses in order to increase their phonon energy and the multiphonon relaxation rate of the Er3+:4I11/2→ 4I13/2 transition, which will allow efficient 980 nm pumping. The inclusion of additional glass components such as GeO2 and Al2O3 has been shown to enhance the thermal stability of the boro-tellurite glasses. No crystallization peak (Tc) was observed in glass samples containing GeO2 and Al2O 3. The suitability of these boro-tellurite glasses as host for broadband erbium-doped fiber amplifiers and their advantages over the other tellurite glasses are discussed.
