Abstract: The present invention, even in the case where the size of a preform itself is increased, enables production of a multi-core optical fiber in which cores are arranged with high accuracy. A plurality of core members each being rod-like are fixed by an array fixing member while a relative positional relation of the plurality of core members is fixed, and the plurality of core members and a cladding member are integrated into one piece, and thus a preform is obtained. By drawing the obtained preform, a multi-core optical fiber in which core arrangement is controlled with high accuracy is obtained.

Abstract: The present invention relates to an optical waveguide manufacturing method, which excels in mass productivity of a planar optical waveguide. In an aggregating step, plural members (20), which have a rod (21) or pipe (22) shape respectively, are arranged and bundled so as to constitute a substantially similar figure to at least a part of a desired waveguide pattern on a cross-section perpendicular to the longitudinal direction of the members (20). The plural members (20) bundled in the aggregating step are, after being softened by heating, elongated in a longitudinal direction thereof in an elongating step, whereby an elongated body is formed. The elongated body formed in the elongating step is cut along a plane perpendicular to the longitudinal direction of the elongated body in a cutting step. By these steps, a planar optical waveguide, on which a waveguide pattern based on a micro-structure is formed, is manufactured.

Abstract: Methods and apparatus relate to optical fibers suitable for use in sensing applications exposed to radiation environments. The fibers include a core of pure silica or chlorine doped silica surrounded by a fluorinated silica cladding. These glasses for the core and cladding utilize dopants that resist radiation-induced attenuation. A two step process for forming the cladding can achieve necessary concentrations of the fluorine by performing a soot deposition process in a different environment from a consolidation process where the soot is sintered into a glass. Concentration of fluorine doped into the cladding layer enables obtaining a numerical aperture that confines a mono-mode of the fiber to resist bend-induced attenuation. Dimensions of the fiber further facilitate bending ability of the fiber.
