    Abstract: A method for manufacturing deuterium-treated silica glass includes exposing silica glass to a deuterium-containing atmosphere for a predetermined period of time to diffuse deuterium molecules within the silica glass, maintaining the silica glass at 40° C. or higher, and cooling the silica glass to room temperature. The silica glass is a silica glass-based optical fiber having a core made of silica glass, where the core is positioned at a center of the optical fiber and contains at least germanium, and a clad made of silica glass, where the clad surrounds the core and has a lower refractive index than the core. A surface of the silica glass is covered with a resin coating.

    Abstract: A method of loading at least one fused silica article with hydrogen. At least one fused silica article is first loaded with an amount of hydrogen so that the hydrogen concentration at the center of the article exceeds a minimum concentration upon completion of loading. An amount of hydrogen is the removed from the fused silica article so that the fused silica article has an average hydrogen concentration that is less than the maximum average concentration limit. The surface region of the fused silica article is then reloaded to ensure that the hydrogen concentration throughout the article is within a predetermined pressure range. A fused silica article comprising hydrogen is also described.
