摘要

Infrared hollow fiber with metal and dielectric inner-coatings has found applications in medical and industrial fields. It is a commonly used method to lower the loss by inner-coating multi dielectric layers. In this paper, SiO_2 and Agl were selected to fabricate the multilayer mid-infrared hollow fiber. Liquid-phase coating techniques were experimentally discussed in order to control the film thickness. It is shown that concentration and flow speed of the coating solution are key parameters to modify SiO_2 film thickness. Agl film was obtained by firstly coating a silver layer and then iodinating the silver layer into Agl. SiO_2 and Agl films were deposited orderly on the inner wall of a 0.7-mm bore glass capillary. Both thicknesses for SiO_2 and Agl films were well controlled and optimized according to the theoretical calculation. The measured infrared loss spectrum of SiO_2/Agl/SiO_2/Ag multilayer hollow fiber has a good agreement with the calculated result and shows band gap effect around the wavelength of 5.3 fim.
