摘要：
Er3+ doped tungsten-tellurite glass (EDWTZn) is prepared, whose host compositions are WO3, TeO2, ZnO and Na2O. 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 1530 nm are 9.52 × 10-21 cm2 and 86 nm, 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 1530 nm can be provided.
