Abstract: Apparatus and methods for bending thin glass sheets are described. The methods and apparatus described include positioning an auxiliary heater between a furnace and an entrance to glass bending station and/or positioning a downstream auxiliary heater between a glass bending station and a quench station. Also described are apparatus and methods for bending thin glass sheets by compensating for heat loss and maintaining the glass viscosity within a workable range for the bending or forming operation. Auxiliary heating elements can be placed in locations that would otherwise provide for excessive heat loss.

Abstract: According to one embodiment two-core optical fiber is provided for use in Brillouin distributed fiber sensor applications and systems. The two-core fiber includes a first and second core. Each core is configured to exhibit a Brillouin frequency shift greater than 30 Mhz relative to the other core. Further, each core possesses temperature and strain coefficients that differ from the other core. The cores can be configured to produce Brillouin frequency shift levels of at least 30 Mhz relative to one another. These differences in shift levels may be affected by adjustment of the material compositions, doping concentrations and/or refractive index profiles of each of the cores. These optical fibers may also be used in BOTDR- and BOTDA-based sensor systems and arrangements.

Abstract: The channel waveguides disclosed herein have bend compensation in the form of at least one compensated bend section. The channel waveguides are formed in a glass-based substrate having a glass-based matrix. The channel waveguide has an waveguide IOX region with a straight section and a bend section. The waveguide IOX region at the bend section is superimposed with a quasi-linear modifying IOX region to form a compensated bend IOX region that defines the compensated bend section. The compensated bend section has a reduced amount of optical loss as compared to if the compensated bend section had a refractive index profile that was the same as the straight section. Methods of forming the compensated bend sections for the channel waveguides are also disclosed.

The blocking coating includes a light absorber that does not transmit light with wavelengths from greater than or equal to about 250 nm to less than or equal to about 400 nm; The light absorber is positioned such that light having a wavelength from greater than or equal to about 190 nm to less than or equal to about 500 nm is not incident to the adhesive. The adhesion promoter improves adhesion of the blocking coating to the optical element and reduces the likelihood of delamination during handling, operation, or clearing of the optical assembly.

Abstract: Methods of forming a ferrule are disclosed where the ferrule includes an inner member and an outer member. An optical fiber is secured in an axial bore of the inner member, and then offset of a core of the optical fiber from a geometric center of the inner member is determined. The outer member is then formed over the inner member to “correct” for this offset so that the core of the optical fiber ends up closer to the geometric center of the resulting ferrule. Related ferrules and cable assemblies including the same are also disclosed.
