Abstract: The present disclosure is directed to a method of making an optical fiber with improved bend performance, the optical fiber having a core and at least one cladding layer, and a chlorine content in the in the last layer of the at least one cladding layer that is greater than 500 ppm by weight. The fiber is prepared using a mixture of a carrier gas, a gaseous chlorine source material and a gaseous reducing agent during the sintering of the last or outermost layer of the at least one cladding layer. The inclusion of the reducing gas into a mixture of the carrier gas and gaseous chlorine material reduces oxygen-rich defects that results in at least a 20% reduction in TTP during hydrogen aging testing.

Abstract: What is disclosed includes OD-doped synthetic silica glass capable of being used in optical elements for use in lithography below about 300 nm. OD-doped synthetic silica glass was found to have significantly lower polarization-induced birefringence value than non-OD-doped silica glass with comparable concentration of OH. Also disclosed are processes for making OD-doped synthetic silica glasses, optical member comprising such glasses, and lithographic systems comprising such optical member. The glass is particularly suitable for immersion lithographic systems due to the exceptionally low polarization-induced birefringence values at about 193 nm.

Abstract: The invention provides a method of making an optical fiber preform using a modified chemical vapor deposition process by flowing glass precursor gases through a preform tube for depositing glass material therein, and simultaneously flowing heavy water vapors through the preform tube for incorporating deuteroxyl groups into the glass material. Then, the preform tube is controllably heated so as to effect a collapse of the preform tube into a rod. Advantageously, optical fibers drawn from such preforms have an increased resistance to hydrogen and will not require passivation.
