Abstract

We demonstrate microstructuring of chalcogenide fiber facets in order to obtain enhanced transmission due to the antireflective properties of the microstructured surfaces. A variety of molding approaches have been investigated for As(2)S(3) and As(3)Se(3) fibers. Transmission as high as 97% per facet was obtained in the case of As(2)S(3) fiber, compared to the native, Fresnel-loss limited, transmission of 83%.

摘要

我们展示了硫族化物光纤端面的微结构化，以便由于微结构化表面的抗反射特性而获得增强的传输。针对As₂S₃和As₃Se₃光纤研究了多种成型方法。对于As₂S₃光纤，每个端面的传输率高达97%，相比之下，原始的菲涅尔损耗限制传输率为83%。
