    Abstract: This invention is directed to photosensitivity opacifiable glasses requiring very short exposures to ultraviolet radiation to effect the development of opacity therein during a subsequent heat treatment thereof. The glasses consist essentially, expressed in terms of weight percent on the oxide basis, of about 14 18% Na2O, 0-6% ZnO, 6-12% Al2O3, 0-5% B2O3, 65-72% SiO2, and 0-0.2% Sb2O3, and 0.007-0.04% Ag, 0.008-0.05% Ceo2, 0.7-1.25% Br, and 1.5-2.5% F as analyzed in the glass, the sum of those components constituting at least 90% of the total composition.

    Abstract: An athermal optical device and a method for producing the device, such as an athermal optical fiber reflective grating, are described. The athermal optical fiber reflective grating device comprises a negative expansion substrate, an optical fiber mounted on the substrate surface, and a grating defined in the optical fiber. The method for producing the athermal optical fiber reflective grating device comprises providing a negative expansion substrate, mounting an optical fiber with at least one reflective grating defined therein onto the substrate upper surface, and affixing the optical fiber to the substrate at at least two spaced apart locations.
