High Strength, Long Length Optical Fibers Increased Durability of Optical Fiber through the Use of Compressive Cladding.
Abstract
The durability of optical fiber waveguides has been improved by employing a surface compressive cladding technique. The durable fibers having a very thin surface compressive layer of either pure silica or Ti-doped silica were fabricated based on the developed computer models of the three-layer and the four-layer structure fibers. Surface compressive stresses greater than 100 kpsi (0.69 GPa) were deduced from the static fatigue and bend test results of the fibers having higher thermal expansion coefficients in inner layers with a thin Ti-doped silica surface layer.
