Radiation Hardened Silica-Based Optical Fibers
Abstract
Since it is generally recognized that radiation-induced loss is due to pre-existing defects in optical fiber, the technical approaches were designed to reduce the number of these defects in as-drawn fiber and to passivate the ones that remain. While our investigations confirmed the Ge doping leads to greater sensitivity, both the experimental and theoretical results remain ambiguous as to whether fluorine is beneficial or deleterious. The diffusion of impurities from the preform substrate tube into the core has been identified as an important source of induced loss. Hydrogen treatment has been found to be an effective means of passivating defects in as-drawn fiber, and improved the hardness of most fibers tested.
