We summarize the development of integral equations and their numerical implementations in solving wave propagation in a cylindrical fiber with concentric dielectric layers. These multilayered fibers are also called Bragg fibers [12,13,15]. From preliminary computational results, we find that an air-core multilayered fiber can effectively guide wave in its air core when its total radius is a quarter of the operating wavelength.
