Non-Conducting Hermetic Coatings for Optical Fibers
Abstract
A number of military systems incorporating fiber optics require long lengths of high strength fibers. These fibers, like other silicate derived glasses, suffer from the phenomenon of stress corrosion or static fatigue. The observed fatigue occurs when fibers are subject to tensile stresses in a humid environment. None of the currently used organic buffer and overcoating materials is impermeable to water and, therefore, to provide hermetic protection, one must look to other materials. Among the more promising materials are metals, silicon nitride, and diamond-like carbon. The requirements and possible behavior of suitable coatings will be discussed in terms of performance, expected reliability, and economic considerations.
