Abstract: A method of forming an alkali metal oxide-doped optical fiber by diffusing an alkali metal into a surface of a glass article is disclosed. The silica glass article may be in the form of a tube or a rod, or a collection of tubes or rods. The silica glass article containing the alkali metal, and impurities that may have been unintentionally diffused into the glass article, is etched to a depth sufficient to remove the impurities. The silica glass article may be further processed to form a complete optical fiber preform. The preform, when drawn into an optical fiber, exhibits a low attenuation.

Abstract: A refractory dielectric body is heated with a plasma torch at conditions which do not result in substantial removal of a surface portion of the body, yet which are sufficient to reduce both surface and bulk impurities. Typically, the body is solid, e.g., a rod as opposed to a tube, and is treated with the plasma in the absence of simultaneous deposition of material onto the body. Advantageously, an isothermal plasma torch is utilized, and the torch advantageously produces an oxygen or oxygen-containing plasma. The invention is useful for reducing chlorine impurities by at least about 30% to a depth of at least about 10 .mu.m, with accompanying reduction of hydroxyl impurities. The invention thus provides a useful method for reducing the concentration of impurities that contribute to imperfections during the process of drawing fiber from an optical fiber preform, without requiring substantial removal of the surface of the preform.

Abstract translation: 耐火电介质体在等离子体焰炬的条件下被加热，其条件不会导致本体的表面部分的实质去除，而这足以减少表面和体积杂质。 通常，身体是固体的，例如与管相反的杆，并且在没有材料同时沉积到身体上的情况下用等离子体处理。 有利地，使用等温等离子体焰炬，并且炬有利地产生含氧或含氧的等离子体。 本发明可用于将氯杂质减少至少约30％至至少约10μm的深度，伴随着羟基杂质的减少。 因此，本发明提供了一种有用的方法，用于在从纤维预制棒中拉伸纤维的过程中减少有助于缺陷的杂质的浓度，而不需要基本上去除预型体的表面。
