    摘要: A single-polarization single-mode optical fiber comprises a core made of silica glass, a clad surrounding the core and made of silica glass having a smaller index of refraction than the glass comprising the core, a pair of stress applying members symmetrically disposed on the clad and made of silica glass having different thermal expansion coefficient from that of the clad, spacers interposed between the stress applying members and made of silica glass having substantially the same thermal expansion coefficient as the clad, and a jacket surrounding the spacers, stress applying members. The jacket is also made of silica glass and has a smaller expansion coefficient than the stress applying members. The optical fiber of this invention has an excellent polarization preserving characteristic, low loss, long length, and stable characteristics.

    摘要: The present invention relates to a multimode optical fiber which can provide a smooth cut face suitable for fusion splicing between fibers. The multimode optical fiber has at least a core extending along a central axis and having an α-power refractive index profile, and a cladding, and a residual stress distribution in the core along a radial direction from the central axis has a shape with a maximum at a position intersecting with the central axis.

    摘要: A method for making a glass ceramic, optoelectronic material such as a clad optical fiber or other component for use in an optoelectronic device. The method comprises preparing a glass composition batch to yield a precursor glass for a nanocrystalline glass-ceramic that is doped with at least one kind of optically active ion, such as a transition metal or lanthanide element; melting the batch; forming a glass cane; surrounding the cane with a chemically inert cladding material shaped in the form of a tube; drawing a glass fiber from the combined precursor-glass “cane-in-tube” at a temperature slightly above the liquidus of the precursor glass composition, and heat treating at least a portion of the drawn clad glass fiber under conditions to develop nanocrystals within the core composition and thereby forming a glass ceramic.

    摘要: In an optical component having a cylindrical core of quartz glass and a coaxial jacket of quartz glass containing a dopant which decreases the index of refraction, the jacket glass contains a viscosity-increasing stiffening agent to reduce tensile strength on the core at drawing temperature of 1000.degree. to 2500.degree. C. or a relaxation agent for lowering the viscosity of the quartz glass in a concentration which is lower than that present in the core glass.
