    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: Ion-exchangeable glasses having high hardness and high elastic modulus. The base cover glass formulation includes Na2O, Y2O3, Al2O3, and SiO2. The glasses may further include P2O5, B2O3, and any of the alkali, alkaline earth, and rare earth oxides, as well as other divalent metal oxides. The ion-exchangeable glasses offer higher hardness, which provides more resistance to micro-ductile scratching damage. Ion-exchange of these glasses increases their resistance to cracking caused by frictive damage and increases retained strength following formation of surface damage.
