The methods generally include contacting an alkali-containing glass article having a first alkali metal cation with a molten salt bath including from 0.1 wt. % to 3 wt. % nanoparticles and at least one alkali metal salt having a second alkali metal cation that has an atomic radius larger than an atomic radius of the first alkali metal cation. The nanoparticles may include at least one of metalloid oxide nanoparticles and metal oxide nanoparticles. The methods also include maintaining contact of the glass article with the molten salt bath to allow the first alkali metal cations to be exchanged with the second alkali metal cations of the molten salt bath. Further, the methods may include removing the glass article from contact with the molten salt bath to produce a strengthened glass article. A Surface Hydrolytic Resistance titration volume of the strengthened glass article may be less than 1.5 mL.

A method of treating a substrate in a pressure vessel that includes the steps: preparing an ion-exchange bath with a bath composition that comprises a polar solvent and a plurality of ion-exchanging ions in a vessel; submersing a substrate having an outer region containing a plurality of exchangeable ions in the bath; pressurizing the bath in the vessel to a predetermined pressure substantially above ambient pressure; heating the bath in the vessel to a predetermined temperature; and treating the substrate for a predetermined ion-exchange duration at the predetermined pressure and temperature such that a portion of the plurality of exchangeable ions is exchanged with a portion of the ion-exchanging ions. The substrate can consist essentially of a glass, glass-ceramic or ceramic substrate composition, and the predetermined ion-exchange duration, temperature and pressure can each be selected based at least in part on the substrate composition and the bath composition.

Phosphorus-silicate fibers suitable for extended band amplification

Suppression of stimulated Brillouin scattering (SBS) by broadening the energy spectrum of participating SBS photons and/or phonons is achieved in an optical fiber having a core with both radially nonuniform viscosity and CTE profiles provided by alternating layers of glass modifying dopants such as phosphorous and fluorine. The nonuniform thermal expansion and viscosity profiles impart a residual, permanent, nonuniform stress in the fiber. The SBS suppressing effect provided by the nonuniform stress can be controlled and enhanced by applying a uniform or nonuniform tensile force to the fiber as it is being drawn. A preform for the fiber is also disclosed.

A single mode waveguide coupling to a multimode fiber of a high-bandwidth local optical network is made by a tapered coupler that expands the spot size of the propagating beam to fill additional modes of the multimode fiber. The tapered coupler has a core surrounded by inner and outer layers of cladding. The core and the inner cladding layer are drawn down along their length to force light from the core into the surrounding inner cladding layer. The outer cladding layer confines the expanded beam within the core and inner cladding layer.
