    Abstract: The present invention provides an optical fiber providing high photosensitivity in the absence of hydrogen loading as well as a low numerical aperture. One aspect of the present invention relates to an optical fiber including a core (22), the core comprising silica doped with at least about 6mol% germania and at least about 0.9wt% fluorine; and a cladding (24) surrounding the core. The optical fiber of the present invention is suitable for the production of fiber Bragg gratings.

    Abstract: Optical wave guides made of quartz glass with reduced infrared absorption and reduced attenuation coefficients are made of a glass which consists of atoms with a mass-number higher than that of the natural isotope ratio. The quartz glass or doped quartz glass consists of silicon atoms of which most or all have the mass-numbers 29 and/or 30, as well as oxygen atoms of which most or all consist of isotopes with the mass-numbers 17 and/or 18. For doping with germanium atoms with higher mass-numbers than in the natural isotope mixture, atoms of the 76Ge isotope are preferably used. For optical wave guides based on quartz glass with attenuation coefficients below 0.15 dB/km, glass with atoms of preferably 30Si and/or 18O are preferably used. Such optical wave guides are also suitable for transmitting high-energy, pulsed or continuous laser light in a wavelength range from 2.0 to 3.0 νm. These optical wave guides are also suitable for transmitting holmium laser light of 2.1 νm and er laser light with a wavelength equal to 2.79 and 2.94 νm.

    Abstract: A process is described for making organometallic complexes suitable for use in the production of glass or ceramic articles by a vapour phase oxidation process.
    The complex has the formula M(hfa)₂.nTHF wherein M is Mg or Zn, hfa is hexafluoroacetylacetonate, THF is tetrahydrofuran and n is 2 which is prepared by

    (a) providing an adduct of the complex M(hfa)₂ which comprises one or more adducted water molecules;
    (b) dissolving the water-containing adduct in excess THF to form a reaction mixture wherein the adduct will react with the THF to replace the adducted molecules by THF;
    (c) evaporating the reaction mixture to dryness to form a solid residue; and
    (d) collecting the M(hfa)₂.nTHF product from the residue by sublimation of the residue.
