Paper Abstract

We report the optimal design for hollow fiber inner-coated with metallic and multi-dielectric layers by using ray-optics theory. Transmission characteristics of the multilayer hollow fiber are more dependent on the film surface roughness in infrared region. Comparisons of fibers with smooth and rough films are made and discussed in detail. The optimal design for film thickness, inner radius, the number of layers and refractive indices is presented. The calculation results are important for structure design, material selection and further fabrication of metallic multilayer hollow fiber when considering imperfections in film coating techniques.
