制备了一种新型的可应用于1.5μm通讯窗口宽带放大自发辐射光源的掺铒碲酸盐玻璃单模光纤(EDTF), 并分析了其热学性质和光谱特性. 该玻璃显示了良好的热稳定性(Δ T>150℃)和匹配的热膨胀系数. 采用自制EDTF短光纤, 组装了超荧光单程反向结构光源(SPB),利用波长为980nm的半导体激光器抽运掺Er³⁺的碲酸盐短光纤, 可在1450～1650nm范围获得宽带宽的铒离子放大自发辐射光谱(ASE). 研究了光纤长度, 泵浦功率等对放大自发辐射光谱的影响. 研究结果显示, 该碲酸盐玻璃是一种适用于宽带放大自发辐射光源的基质材料.

Fabrication and characterization of a newly erbium-doped single-mode tellurite glass-fiber applicable for 1.5μm amplified spontaneous emission (ASE) source were reported. The glasses exhibit very good thermal stability (Δ T>150℃) and matchable thermal expansion coefficient. A very broad erbium amplified spontaneous emission in a range of 1450-1650nm from erbium-doped single-mode tellurite glass-fiber is obtained upon excitation of a 980nm laser diode. Effects of the length of glass-fiber and the pumping power of laser diode on the amplified spontaneous emission are discussed. The result indicates that the tellurite glass-fiber is a promising candidate for designing fiber-ASE source.
