    Abstract: An optical fiber is provided that includes a fiber configured to transmit optical data in a plurality of modes or in a single mode; a core region in the fiber that comprises fluorine-doped silica; and a cladding in the fiber that surrounds the core region and that comprises fluorine-doped silica. The core region has a graded refractive index profile with an alpha of about 0.5 to 5. The core of the fiber may be set with a radius of approximately 6 to 50 microns. The cladding may also comprise one or a plurality of layers, including trench or moat regions of a relatively lower refractive index. Still further, an inner cladding may be doped with fluorine at a concentration greater than that in the core region. An outer cladding can comprise silica with fluorine at a concentration below or equal to that in the inner cladding.

    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.
