Article comprising a fiber bundle, and method of making the article

摘要

Optical fiber bundles having high optical throughput can be produced with relatively high yield if gaps between fibers are eliminated by application of a particle-containing glass precursor material, exemplarily fumed silica in an aqueous medium. Manufacture of optical fiber bundles that comprise two or more fibers that each comprise a substantially planar surface (with the planar surfaces facing each other) is improved by application of a particle-free glass precursor material, e.g., partially hydrolysed tetramethyl orthosilicate, to the fiber bundle. After drying of the applied glass precursor material the fiber bundle is heated to fuse the fibers together.
