中文摘要：

密集波分复用（DWDM）技术的快速发展和应用，对光纤放大器的宽带特性也提出更高的要求。最近有研究发现，铋离子在某些玻璃基质能产生发光中心波长位于1．3μm附近、荧光半高宽（FWHM）达300m左右、荧光寿命可达600μs的近红外宽带发光，使得铋离子掺杂的玻璃基质有可能成为未来全波段光纤放大器增益介质。近3年来研究者围绕着铋离子在不同玻璃基质的发光特性，以及铋离子发光机制进行了大量的研究，取得了很大的进展。本文对铋离子掺杂的玻璃发光研究进展进行了综述。

英文摘要：

With the rapid development and application of DWDM technique, more and more demand is put forward for the wider bandwidth of optical amplifiers. Recently, some bismuth ion-doped glasses exhibit 300nm bandwidth around 1.3μm, and its fluorescent lifetimes are always longer than 600μs. Therefore, those bismuth ions-doped glasses are now promising candidates as gain medium for use in the super bandwidth optical amplifiers. In last three years, many researches have given much attention to the spectroscopic properties and emission mechanism of bismuth ions in different, and much more progress had been gained. In this paper, its latest research progress was overviewed.
