Process of Study on Tellurite Glass for Broadband Amplifier
宽带放大器用碲酸盐玻璃研究进展

As host materials for use in Er-doped fiber amplifier(EDFA) and Tm-doped fiber am-plifier(TDFA), tellurite glasses have played an important role in active optical fiber for broadband amplification. This paper summarizes the process of study on composition, structure, thermal stability and spectroscopic properties of tellurite glasses, and discusses their development prospects.
