摘要

以WO

、TeO

、ZnO和Na

O为基质制备了掺Er

钨碲(EDWTZn)玻璃.差热分析表明EDWTZn玻璃的转变温度达到427℃

比常规碲酸盐玻璃具有更高的热稳定性.McCumber原理研究的结果显示

EDWTZn玻璃在1530nm处的峰值受激发射截面和荧光发射半高宽分别为9.52×10

-21

和86nm.数值模拟结果表明

EDWTZn光纤放大器利用较短的激活长度就可获得足够的信号光放大

在1530nm波长附近能提供极宽的平坦增益带

当输入信号光功率为0dBm时

在大约70nm带宽范围内的平均信号增益大于20dB

不平坦度小于5dB.

Abstract

doped tungsten-tellurite glass (EDWTZn) is prepared

whose host compositions are WO

TeO

ZnO and Na

O.The differential thermal analysis shows that compared with the traditional glasses

the thermal stability of EDWTZn glass is higher.The results analyzed by McCumber theory also show that the peak stimulated emission cross section and the FWHM of EDWTZn glass around 1530nm are 9.52×10

-21

and 86nm

respectively.As for the EDWTZn optical fiber amplifier

the results of numerical simulation show that large amplified signals can be obtained with a shorter length of fiber

and about 70nm flat gain band around 1530nm can be provided.
