Abstract: A vaporizer for halide-free, silicon-containing liquid reactants used in producing preforms is provided. The vaporizer includes a heated, vertically-oriented expansion chamber (20) and a vertical hollow shaft (42) which extends into the chamber and has a plurality of orifices (45) at its upper end (44). Preheated reactant is supplied to the vertical shaft (42) at an elevated pressure and is sprayed onto the chamber's heated wall (22) by the orifices (45). A portion of the liquid reactant vaporizes upon entering the internal volume (24) of the chamber (20) due to the pressure drop between the inside of the shaft and the inside of the chamber. The remainder of the liquid reactant vaporizes by being heated through contact with the chamber's wall (22). Higher molecular weight species present in the raw material or generated by the vaporization process are collected in the bottom portion of the chamber where they can be periodically removed.

Abstract: A dispersion compensating fiber is provided which is capable of reducing the birefringence of the core caused in spinning to suppress an increase in polarization mode dispersion due to the birefringence of the core even though the surface of the core rod is ground to shape the profile of the core during manufacturing.

The variation in circumferential concentration of germanium at the periphery of the core 1 is set at 0.05% or smaller in relative refractive index difference value.

Abstract: An optical fiber having a core for propagating light, where the core includes first, second and third regions. The first, second and third regions are concentrically arranged with the second region around the first region and the third region around the second region. The third region includes a dopant for increasing the refractive index of the third region. The first region includes a first dopant for providing an amplification band and a second dopant for expanding the amplification band. The second region has an impurity concentration which is lower than the concentration of the dopant in the third region and is lower than the concentrations of the first and second dopants in the first region. Upon production of the fiber, the second region acts as a barrier to prevent diffusion of dopants. As a result, the amplification band can be effectively expanded. Various other arrangements of core and clad regions and dopants are provided. An optical amplifier using the various types of fibers is disclosed, as is a fiber having a structure which reduces loss when spliced to another fiber, and a method for splicing the fibers together.

Abstract: A method for producing a glass preform for use in the fabrication of an optical fiber which comprises inserting a core rod made of quartz glass in a cladding tube made of quartz glass added with fluorine, heating them from the outside of the cladding tube to fuse them together to form a primary glass preform comprising a core rod and a first cladding layer around the core rod, depositing SiO.sub.2 soot particles around the primary glass preform and thermally treating the soot deposited glass preform in the presence of a fluorine-containing compound to form a final glass preform from which an optical fiber is fabricated. From the glass preform produced by this method, an optical fiber having low attenuation of light transmission in a wide range of wave-length is fabricated.

Abstract: The present invention relates to a technique for producing polarization-preserving and single polarization optical fibers. As disclosed, high birefringence is introduced into the preform by deforming the fiber preform such that a cladding layer becomes flat and highly conformable, while the core remains hard and substantially round. In particular, a cladding layer with a relatively low melting point is utilized such that when the preform is heated the cladding becomes liquified while the core remains solid. The preform may then be deformed so that the cladding layer is substantially flattened. Standard drawing techniques may then be utilized to form polarization-preserving fibers and single polarization fibers from the preform.
