    摘要: An optical fiber silica glass base material comprising a core formed of silica glass doped with a positive dopant that increases a refractive index; an intermediate layer adjacent to the core and surrounding the core on a radial outside thereof; a trench layer adjacent to the intermediate layer, surrounding the intermediate layer on a radial outside thereof, and formed of silica glass doped with a negative dopant that decreases a refractive index; and a cladding layer adjacent to the trench layer, surrounding the trench layer on a radial outside thereof, and formed of silica glass. Thickness of the intermediate layer in a radial direction is greater than thickness of the trench layer, and a region of the intermediate layer nearer the core is more heavily doped with the positive dopant and/or a region of the intermediate layer nearer the trench layer is more heavily doped with the negative dopant.

    摘要: This disclosure is directed to a silica-titania-niobia glass and to a method for making the glass. The composition of the silica-titania-niobia (SiO2—TiO2—Nb2O5) glass, determined as the oxides, is Nb2O5 in an amount in the range of 0.005 wt. % to 1.2 wt. %, TiO2 in an amount in the range of 5 wt. % to 10 wt. %, and the remainder of glass is SiO2. In the method, the STN glass precursor is consolidated into a glass by heating to a temperature of 1600° C. to 1700° C. in flowing helium for 6 hours to 10 hours. When this temperature is reached, the helium flow can be replaced by argon for the remainder of the time. Subsequently the glass is cooled to approximately 1050° C., and then from 1050° C. to 700° C. followed by turning off the furnace and cooling the glass to room temperature at the natural cooling rate of the furnace.

    摘要: A titania-doped quartz glass suited as an EUV lithographic member is prepared by feeding a silicon-providing reactant gas and a titanium-providing reactant gas through a burner along with hydrogen and oxygen, subjecting the reactant gases to oxidation or flame hydrolysis to form synthetic silica-titania fine particles, depositing the particles on a rotating target, and concurrently melting and vitrifying the deposited particles to grow an ingot of titania-doped quartz glass. The target is retracted such that the growth front of the ingot may be spaced a distance of at least 250 mm from the burner tip.

    摘要: A TiO2—SiO2 glass ingot having a desired TiO2 concentration is fabricated, a sample is cut from the TiO2—SiO2 glass ingot, OH concentration C(OH), TiO2 concentration C(TiO2) and fictive temperature TF of the sample are measured, and zero-CTE temperature T(zero-CTE) is calculated from the measured C(OH), C(TiO2) and TF. A judgment is made as to whether the difference ΔT between the zero-CTE temperature T(zero-CTE) and a target value is within a predetermined range. When the difference ΔT is within the predetermined range, it is judged that the TiO2—SiO2 glass ingot has a desired zero-CTE temperature; when the difference ΔT is not within the range, a production condition for the TiO2—SiO2 glass ingot is corrected on the basis of the difference ΔT.
