    Abstract: PROBLEM TO BE SOLVED: To provide a synthetic silica material having a low level of polarization-induced birefringence, a low level of light-induced wavefront distortion, a high level of initial internal transmission, and method for making the same.SOLUTION: The disclosure includes OD-doped synthetic silica glass usable in optical elements for use in lithography at short wavelengths below about 300 nm. The OD-doped synthetic silica glass is found to have significantly lower polarization-induced birefringence value than non-OD-doped silica glass with comparable concentration of OH. Also an optical member comprising such glass and lithographic systems including such optical member are disclosed. The glass is particularly suitable for immersion lithographic systems by virtue of the exceptionally low polarization-induced birefringence values at about 193 nm.

    Abstract: Disclosed is an optical waveguide fiber preform which is an assembly of one or more core rods (14) surrounded by a plurality of clad rods (10). The clad ro ds (10) have a central portion (12) and a surrounding layer (22), in which the refractive index of the central portion is lower than that of the surroundin g layer. The preform is drawn into an optical waveguide fiber that has a two component clad layer. Proper choice of the central portion (12) and surrounding layer provide a waveguide fiber that is endlessly single mode. Alternative embodiments include fibers containing dopants that enhance fiber photosensitivity or which provide stress-induced or asymmetric-refractive- index-induced birefringence in the waveguide fiber.

    Abstract: A cylindrical glass body having a low water content centerline region and method of manufacturing such a cylindrical glass body for use in the manufacture of optical waveguide fiber is disclosed. The centerline region of the cylindrical glass body has a water content sufficiently low such that an optical waveguide fiber made from the cylindrical glass body of the present invention exhibits an optical attenuation of less than about 0.35 dB/km, and preferably less than about 0.31 dB/km at a measured wavelength of 1380 nm. A low water content plug used in the manufacture of such a cylindrical glass body, an optical waveguide fiber having a low water peak, and an optical fiber communication system incorporating such an optical waveguide fiber is also disclosed.

    Abstract: A method of forming an optical fiber preform that includes providing a consolidated glass preform, depositing a layer of silica soot onto the consolidated glass preform to form a composite preform having a consolidated glass portion and a silica soot portion, and exposing the composite preform to an atmosphere containing a concentration of a deuterium compound for a time and at a temperature sufficient to cause the deuterium compound to penetrate the consolidated glass portion without pervading the entire glass portion. Preferably, the deuterium compound penetrates the glass portion to a desired depth.
