    摘要: Unexpectedly large normalized refractive index changes (.DELTA.>10.sup.-5, but possibly even larger than 10.sup.-3) can be obtained in oxide glass, e.g., high-silica glass, by a treatment that comprises exposing at least a portion of the glass at a temperature of at most 250.degree. C. to H.sub.2 or D.sub.2 (partial H.sub.2 or D.sub.2 pressure greater than 1 atmosphere), and irradiating at least a part of the exposed portion with actinic (typically UV) radiation. The method can be used to make optical components that comprise a region (or regions) of raised refractive index, e.g., an in-line refractive index grating in an optical waveguide, a planar optical waveguide, or a phase grating.

    摘要: The specification describes methods for the manufacture of very large optical fiber preforms wherein the core material is produced by MCVD. Previous limitations on preform size inherent in having the MCVD starting tube as part of the preform process are eliminated by removing the MCVD starting tube material from the collapsed MCVD rod by etching or mechanical grinding. Doped overcladding tubes are used to provide the outer segments of the refractive index profile thus making most effective use of the MCVD produced glass and allowing the production of significantly larger MCVD preforms than previously possible.

    摘要: A process for manufacturing an optical fiber includes the steps of heating and drawing material from a hot optical fiber preform; exposing the hot optical fiber to a compound containing carbon for depositing a carbon coating on the moving optical fiber; measuring an electrical property of the carbon coating; and in response to the measured electrical property, changing a parameter of the process for controlling a characteristic of the carbon coating on the moving optical fiber. Featured within the manufacturing method is a method for measuring the thickness of the carbon coating on the moving optical fiber. From the measured thickness of the carbon coating, a control signal is generated for changing one or more of the process parameters for depositing the carbon coating on the optical fiber from a precursor gas. The coated optical fiber continuously moves through the process without any physical contact. No interruption of the production process occurs.
