中文摘要：
光纤放大器具有实时、高增益、宽带、在线、低噪音、低损耗的全光放大功能，是光纤通信系统中必不可少的关键器件，对于实现信息时代的三大目标起着至关重要的作用。但是现有光纤放大器由于原理上的限制存在带宽窄或系统复杂的瓶颈制约，迫切需要开拓新的光放大介质，实现在石英光纤超低损耗波段现有光纤放大器不能或难以实现光放大的波段的光放大，并最终实现用一个泵浦源一根光纤实现整个光通讯波段的光放大。本项目以开发新型超宽带光纤放大器用材料为主要研究目标，选择我们已经做了一些开拓性工作的Bi掺杂玻璃系统，研究其红外宽带发光的物理机制，探索活性离子共掺、气氛等对发光特性的影响规律，优化玻璃组成、光纤几何构型和光纤成型工艺，实现光通讯波段的超宽带光放大，为在宽带光纤放大器的基础研究领域抢占国际科技制高点，参与国际竞争奠定基础。
