    Abstract: A device amplifies light at wavelengths in the vicinity of 1420-1530 nm, using thulium doped silica-based optical fiber. This wavelength band is of interest as it falls in the low-loss optical fiber telecommunications window, and is somewhat shorter in wavelength than the currently standard erbium doped silica fiber amplifier. The device thus extends the band of wavelengths which can be supported for long-distance telecommunications. The additional wavelength band allows the data transmission rate to be substantially increased via wavelength division multiplexing (WDM), with minimal modification to the standard equipment currently used for WDM systems. The host glass is directly compatible with standard silica-based telecommunications fiber. The invention also enables modified silicate based amplifiers and lasers on a variety of alternative transitions. Specifically, an S-band thulium doped fiber amplifier (TDFA) using a true silicate fiber host is described.

    Abstract: The invention relates to a glass excellent in infrared absorption capability and corrosion resistance, and its fabrication process. A compound of divalent copper and a compound of a metal species for a network modifier oxide are introduced in a wet gel. Then, the wet gel is dipped in a dipping solution having a low solubility with respect to the compound of divalent copper and the compound of a metal species for a network modifier oxide for the precipitation in the wet gel of the divalent copper compound and the compound of a metal species for a network modifier oxide, followed by drying and firing. Thus, an infrared absorbing glass comprising 70 to 98 mol % of SiO2, 1 to 12 mol % of CuO and 1 to 18 mol % of a network modifier oxide other than CuO is fabricated.

    Abstract: This invention relates to the discovery of a method for incorporating various oxides into silica-containing porous and nonporous glass materials by dissolving soluble compounds of the additive oxides, characterized as MxOy, into solutions, colloidal solutions, or suspensions of soluble silicates, reacting the mixture with an organic compound, and then firing the thus-formed body at temperatures below the softening point of the particular glass composition for a sufficient length of time to produce the porous body or non-porous glass body containing the added oxides intimately bonded to the silica network.

    Abstract: The invention relates to an optical filter material made of doped quartz glass, which at a low dopant concentration exhibits spectral transmission as high as possible of at least 80% cm−1 for operating radiation of 254 nm, transmission as low as possible in the wave range below approximately 250 nm, and an edge wavelength λc within the wave range of 230 to 250 nm. It was found that this aim is achieved by doping comprising a gallium compound, which in the wave range below 250 nm has a maximum of an absorption band and thus determines the edge wave range λc.
