More particularly, there is described a method of manufacturing an optical fiber preform, which method comprises the steps of providing a substrate tube of silica doped with sufficient chlorine to obtain an OH concentration of less than 100 ppb and doped with sufficient fluorine proportional to the chlorine doping to obtain a refractive index that is lower than that of a natural silica, depositing inner cladding and an optical core inside the substrate tube, collapsing the substrate tube to form a primary preform, and depositing outer cladding of said natural silica on the resulting primary preform. The invention is applicable to manufacturing optical fibers.

    Abstract: High purity silicon oxyfluoride glass suitable for use as a photomask substrates for photolithography applications in the VUV wavelength region below 190 nm is disclosed. The inventive silicon oxyfluoride glass is transmissive at wavelengths around 157 nm, making it particularly useful as a photomask substrate at the 157 nm wavelength region. The inventive photomask substrate is a nulldry,null silicon oxyfluoride glass which contains doped O2 molecules and which exhibits very high transmittance and laser transmission durability in the vacuum ultraviolet (VUV) wavelength region. In addition to containing fluorine and having little or no OH content, the inventive silicon oxyfluoride glass suitable for use as a photomask substrate at 157 nm contains intersticial O2 molecules which provide improved endurance to laser exposure. Preferably the O2 doped silicon oxyfluoride glass is characterized by having less than 1null1017 molecules/cm3 of molecular hydrogen and low chlorine levels.

    Abstract: Fluorine-containing synthetic quartz glass is produced by feeding silica-forming material, hydrogen, and oxygen gases from a burner to a reaction zone, flame hydrolyzing the silica-forming material in the reaction zone to form particles of silica, depositing the silica particles on a rotatable substrate in the reaction zone to form a porous silica matrix, and heating and vitrifying the porous silica matrix in a fluorine compound gas-containing atmosphere. During formation of the porous silica matrix, the angle between the center axes of the silica matrix and the silica-forming reactant flame from the burner is adjusted to 90-120null so that the porous silica matrix has a density of 0.1-1.0 g/cm3 with a narrow distribution within 0.1 g/cm3. The resulting quartz glass has a high transmittance to light in the vacuum ultraviolet region below 200 nm.

    Abstract: The present invention relates to a method of making a preform which can restrain each member from deforming at the time of making, and a method of making an optical fiber with a smaller polarization mode dispersion by utilizing this preform. In the method of making a preform, the collapsing step carried out when making the preform is divided into at least two stages composed of a first step of forming a first collapsed body by collapsing a core rod member and a first cladding tube member, and a second step of forming a new collapsed body by collapsing the first collapsed body and a second cladding tube member. Also, in at least the first step, the collapsed body obtained is elongated, whereas such a plurality of stages of collapsing step and elongation of the resulting collapsed body reduce the outer diameter ratio of the outer member to the inner member to be collapsed, whereby the deformation resulting from the heating at the time of a single collapsing operation and the like is hard to occur. In an optical fiber obtained from thus manufactured preform, the core and cladding are effectively restrained from becoming noncircular, whereby the polarization mode dispersion characteristic, which becomes important in communications based on a WDM system, is improved in particular.

    Abstract: Synthetic quartz glass is produced by feeding a silica-forming raw material gas, hydrogen gas, oxygen gas and a fluorine compound gas from a burner to a reaction zone, flame hydrolyzing the silica-forming raw material gas in the reaction zone to form fine particles of fluorine-containing silica, depositing the silica fine particles on a rotatable substrate in the reaction zone so as to create a fluorine-containing porous silica matrix, and heat vitrifying the porous silica matrix in a fluorine compound gas-containing atmosphere. This process enables the low-cost manufacture of a synthetic quartz glass having a higher and more uniform transmittance to light in the vacuum ultraviolet region than has hitherto been achieved.
