摘　　要：提出一种双包层结构Ge/GeO2介质膜空芯中红外光纤.先采用排布法拉制出包层带有多层空气孔的空芯毛细管,最外层涂有一层硅胶,以加强其机械强度,然后利用化学气相沉积和还原方法在空芯石英毛细管中制备出GeO2-Ge的多层介质反射膜,该膜层提高了Ge/GeO2膜层在短波段的反射效率.经光谱检测分析,该光纤可传输波长为3-12μm,并且中间没有出现大的吸收峰.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 analysis,the fiber transmission wavelength spreads from 3 to 12 μm without apparent absorption.
