摘要：

Er-doped phosphor-tellurite glass for broadband short-length Er-doped fiber amplifier(EDFA)is fabricated and characterized.The differential value(△T)of onset crystalline temperature(T)and glass transition temperature(T)is 206°C.The stimulated emission cross section of Eris calculated from ab- sorption spectrum by McCumber theory and is 0.87×10cm~2 at 1532 nm.A broad 1.5-μm fluorescence spectrum with 54-nm full-width at half maximum(FWHM)is demonstrated.Especially,the maximum phonon energy of undoped phosphor-tellurite glass is 1100 cm,which restricts the upconversion lumines- cence.It is possible to pump efficiently at 980 nm.These results indicate Er-doped phosphor-tellurite glass is suitable for fabricating broadband short-length EDFA.
