Abstract: Methods for growing carbon nanotubes on glass substrates, particularly glass fiber substrates, are described herein. The methods can include depositing a catalytic material or a catalyst precursor on a glass substrate; depositing a non-catalytic material on the glass substrate prior to, after, or concurrently with the catalytic material or catalyst precursor; and exposing the glass substrate to carbon nanotube growth conditions so as to grow carbon nanotubes thereon. The glass substrate, particularly a glass fiber substrate, can be transported while the carbon nanotubes are being grown thereon. Catalyst precursors can be converted into a catalyst when exposed to carbon nanotube growth conditions. The catalytic material or catalyst precursor and the non-catalytic material can be deposited from a solution containing water as a solvent. Illustrative deposition techniques include, for example, spray coating and dip coating.

Abstract: Methods for coating an optical fiber with optical fiber Bragg grating (FBG) with a hermetic coating, particularly a coating of carbon, are employed to avoid ingress of gases, vapors or fluids in the ambient environment. This ingress can be from water or hydrogen, which can diffuse in the fiber glass and cause deviation/drift in the measured Bragg measurements. Bragg gratings that maintain the grating strength at temperatures in excess of 1000° C. are used and can be formed by heating the fiber above 1000° C. in a chamber with a reactive gas that produces deposition of carbon.

Abstract: The present invention relates to a dispersion-managed optical fiber which can be manufactured easily and has a structure which enables the easy connection thereof with other optical fiber and the like. The dispersion-managed optical fiber is a silica-based optical fiber ensuring its single mode at a predetermined wavelength within a signal wavelength band, in which first portions each having a positive chromatic dispersion and second portions each having a negative chromatic dispersion are arranged alternately and adjacent to each other. In the dispersion-managed optical fiber, the dopant concentration is made uniform in the longitudinal direction and, corresponding to the above-mentioned first and second portions, the refractive index of a glass layer not doped with GeO2 as a dopant is adjusted or the residual stresses in glass layers are changed.

Abstract: A method of applying an amorphous boron-based protective coating to an optical fiber comprising an optical core enclosed in optical cladding, both made of a silica-based material, wherein the boron is applied to the surface of said optical fiber chemically from the vapor phase at a temperature lying in the range 1050.degree. C. to 1250.degree. C., by reducing boron chloride BCl.sub.3 by means of hydrogen H.sub.2. The amorphous boron protective coating imparts mechanical protection to the fiber, and enhanced abrasion resistance, enabling the fiber to be used in optical cables of high capacity and that are highly compact. The thickness of the resin coating can be about half that required when a carbon protective coating is used, and can even be eliminated. The coating further provides sealing properties comparable to those provided by a carbon coating.

Abstract: An optical fiber which has just been drawn from an optical preform is provided with two external hermetic coatings. The primary coating is a metallic coating provided by, for example, using a heterogeneous nucleation thermochemical deposition technique. This technique involves passing the fiber through a reaction zone which contains a gaseous medium that includes a reactant which decomposes, or a mixture of reactants which chemically react, at a predetermined temperature to form the material of the coating. The second coating is provided by immersing the fiber in a deposition bath containing a liquid medium which includes at least one reactant capable of deposition onto the primary coating to form a secondary coating. The deposition process may be achieved by applying a current through the medium at a predetermined temperature or by including reactants in the medium which will deposit at predetermined temperatures without applying a current. The resulting fiber may then be provided with an additional polymer coating layer.

Abstract: A process whereby an optical fiber is hermetically coated with a layer of aluminum oxide. The fiber is reacted pyrolytically with organo aluminum derivatives or other aluminum compounds, either in the form of vapor or atomized spray, to produce the desired coating. The thickness can be varied by changing reaction parameters. A buffer is also applied to the coated fiber. The end product is a glass fiber impervious to gases and fluids in the environment, especially H.sub.2 O, and one of improved abrasion resistance, hardness and strength.
