A dual-layer dielectric film of Ge/GeO2 hollow-core mid-infrared fiber was proposed. The capillaries with single circle air holes are made by stack-draw method, which are then covered by a layer of silica gel in the following procedure to increase the mechanical strength of the structure. The dual-layer dielectric reflection films of GeO2-Ge on inner wall of the quartz capillary were deposited by CVD and hydrogen reduction. The reflection efficiency at the short wave band is raised in this way. From the spectrum analysi
