Reduced Fresnel Losses in Chalcogenide Fibers by Using Anti-Reflective Surface Structures on Fiber End Faces

Reduced Fresnel Losses in Chalcogenide Fibers by Using Anti-Reflective Surface Structures on Fiber End Faces

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 As2S3 and As2Se3 fibers. Transmission as high as 97% per facet was...

Zusammenfassung: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 As2S3 and As2Se3 fibers. Transmission as high as 97% per facet was obtained in the case of As2S3 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?. Published in Optics Express v18 n25, 6 Dec 2010.
