Abstract

We demonstrate microstructuring of chalcogenide fiber end faces 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(2)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%. The potential for hydrophobic character was also demonstrated by increasing the contact angle of water droplets to greater than 120°.

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。已经针对As(2)S(3)和As(2)Se(3)光纤研究了多种成型方法。对于As(2)S(3)光纤，每个面的传输率高达97%，相比之下，原生的、受菲涅尔损耗限制的传输率为83%。通过将水滴的接触角增加到大于120°，还证明了其具有疏水特性的潜力。
