Paper Abstract

An idea of an equivalent refractive index for the ray tracing calculation of hollow core waveguides is proposed. A virtual, complex refractive index is uniquely found by minimizing the difference between reflectivity of a virtual monolayer material and a metal substrate coated with a dielectric film. By using this technique, transmission losses of a delivery system consisting of a hollow fiber and a tapered hollow waveguide are calculated.
