    Abstract: Known is a method for producing synthetic quartz glass comprising the following method steps: (a) reacting a carbonic silicon compound-containing raw material with oxygen in a reaction zone into SiO
    2 particles, (b) precipitating the SiO2 particles on a sedimentation area by forming a porous SiO2 soot body containing hydrogen and hydroxyl groups, (c) drying the porous SiO2 soot body, and (d) glazing to the synthetic quartz glass by heating the soot body up to a glazing temperature. In order to indicate a method proceeding therefrom which facilitates a cost-efficient production of quartz glass by means of pyrolysing or hydrolysing a carbon-containing silicon compound using a carbon-containing raw material, the invention describes the production of a soot body with a carbon content within the range of 1 ppm by weight to 50 ppm by weight.

    Abstract: 5n7 Disclosed is a method and apparatus for drawing an elongated glass article (32) such as a fiber optic device. The article (32) is drawn upwardly from a source (28) through the surface of a quantity of molten metal (21) having a vertical temperature gradient. The source can be an elongated solid glass preform (28) that is vertically positioned within the molten metal (21) such that the temperature of that portion of the molten metal adjacent the upper end region is sufficiently high to heat that region to drawing temperature. The upper end region (29) is pulled to form a tapered root, continued pulling resulting in the formation of an elongated article (32) from the small diameter root end. The relative position of the root is maintained with respect to the surface of the molten metal during the drawing operation. Alternatively, the glass can be drawn from an orifice located within the molten metal.
    The apparatus includes container means (11,12) for supporting the molten metal (21), and external or internal means (22,23) for heating and/or cooling portions of the molten metal (21). The container (11,12) can also be provided with baffle means for dividing the container into a plurality of chambers.

    Abstract: The apparatus is composed of two coaxial crucibles (3, 4) the outer one (4) presenting a low-softening temperature, so that it might be drawn with the raw materials. Thus a fibre is obtained with an outer coating which protects it against atmospheric agents. According to this process raw materials are used allowing the fabrication of fibres which may be used to transmit optical radiations with wavelengths longer than 5 µm; with an attenuation minimum lower than 10- 3 dB/km.

    Abstract: To overcome problems of fabricating conventional core-clad optical fibre from non-silica based (compound) glass, it is proposed to fabricate non-silica based (compound) glass optical fibre as holey fibre i.e. one contining Longitudinal holes in the cladding. This removes the conventional problems associated with mismatch of the physical properties of the core and clad compound glasses, since a holey fibre can be made of a single glass composition. With a holey fibre, it is not necessary to have different glasses for the core and cladding, since the necessary refractive index modulation between core and cladding is provided by the microstructure of the clad, i.e. its holes, rather than by a difference in materials properties between the clad and core glasses. Specifically, the conventional thermal mismatch problems between core and clad are circumvented. A variety of fibre types can be fabricated from non-silica based (compounds) glasses, for example: single-mode fibre; photonic band gap fibre; highly non-linear fibre; fibre with photosensitivity written gratings and other refractive index profile structures; and rare-earth doped fibres (e.g. Er, Nd, Pr) to provide gain media for fibre amplifiers and lasers.

    Abstract translation: 为了克服从非二氧化硅（复合）玻璃制造常规的包芯光纤的问题，提出了制造非二氧化硅基（复合）玻璃光纤作为多孔纤维，即在包层中连续的纵向孔。 这消除了与芯和包覆复合玻璃的物理性能失配相关的常规问题，因为多孔纤维可以由单一玻璃组合物制成。 使用多孔纤维，由于芯和包层之间必需的折射率调制是通过包层的微结构（即其孔）而不是材料性质的差异来提供的，因此不需要具有用于芯和包层的不同的玻璃 在包层和核心眼镜之间。 具体来说，芯和包层之间常规的热失配问题被规避。 各种纤维类型可以由非二氧化硅（化合物）玻璃制成，例如：单模纤维; 光子带隙光纤; 高度非线性的纤维; 具有感光性的光纤写入光栅和其他折射率分布结构; 和稀土掺杂光纤（例如Er，Nd，Pr），为光纤放大器和激光器提供增益介质。
