我们报道了低损耗硫系微结构光纤（MOF）制造的重大进展。这种新方法包括在由毛细管和毛细管导向器制成的二氧化硅铸件中模制玻璃，允许开发各种光纤设计，例如悬浮芯、大芯或小芯MOF。在氢氟酸浴中取出铸件后，对预制件进行拉伸，并使用在孔中施加压差的系统来控制设计。纤维损失是硒基MOF迄今为止记录的最低损失，等于材料损失，这意味着该工艺对玻璃质量没有影响。(C)2010年美国光学学会
We report significant advances in the fabrication of low loss chalcogenide microstructured optical fiber (MOF). This new method, consisting in molding the glass in a silica cast made of capillaries and capillary guides, allows the development of various designs of fibers, such as suspended core, large core or small core MOFs. After removing the cast in a hydrofluoric acid bath, the preform is drawn and the design is controlled using a system applying differential pressure in the holes. Fiber losses, which are the lowest recorded so far for selenium based MOFs, are equal to the material losses, meaning that the process has no effect on the glass quality.
