平均配位数为2.45~2.50的 Ge-As-Se 硫系玻璃具有优异的红外透光性能、较高的三阶光学非线性和极低的光致折射率变化效应,是较理想的红外光学非线性材料。采用动态蒸馏技术制备了高纯 Ge-As-Se 玻璃,采用棒管法拉制了芯包结构的光纤。光纤在2~8μm传输性能良好,背景损耗约1 dB/m,杂质对应的峰值损耗约6 dB/m。

Ge-As-Se chalcogenide glasses with MCN of 2.45-2.5 are promising nonlinear optical materials in in-frared regions since they exhibit excellent infrared transparency,high third-order nonlinearity,and ultra-low photo-induced refractive index change.We therefore fabricated high purity Ge-As-Se glasses using a dynamic distillation technique,and drew core/cladding fibers through the rod-in-tube approach.The fibers show good transmittance in the 2-8μm spectral region.The background loss was around 1 dB/m,and the impurity related peak loss was about 6 dB/m.
