摘要： The present invention consists of a method and a structure formed by such method relating to optical fibers. Specifically, the invention consists of a chemical mill process for shaping the end of a fiber and thereby simultaneously forming both lens and precision mounting region. Also described is a self-aligning structure with integral lens. Both features improve light coupling. The lens focuses light energy entering and exiting the fiber. The precision mounting region facilitates alignment of fiber at couplings.

摘要： An improved coating for optical fibers and a method for applying the improved coating are described. The present invention is a dimensionally precise and uniform coating with low-porosity. The improved coating is applied via sputtering within a vacuum chamber. Environmental conditions are monitored within a cylindrical magnetron during sputtering. Sputtering is adjusted or temporarily ceased when environmental conditions approach a damage threshold. Sputtered particles within a plasma cloud are dimensionally similar and adhere to an optical fiber in a volume efficient arrangement forming a more precise, denser, and more adherent coating. Embodiments of the present invention provide improved pull strength by compressively constraining the optical fiber within the coating and by closing microcracks.
