Metal-coated Optical Fibers with High Temperature-resistance and Analysis of Thermal Stresses

The purposes,characteristics and process of metal-coated optical fibers with high temperature-resistance are introduced.The thermal stresses in metal-coated optical fibers are analyzed.The physical properties(Young’s modulus,Thermal expansion coefficient,Poisson’s ratio) of the metal coating and its thickness had an effect on thermal stresses is discussed.There is an optimal design by appropriately selecting physical properties of the metal coating and its thickness.
