本文报道了具有AgI和SiO2多层内涂层的红外中空光纤在中红外波段的传输特性。制备了SiO_2-AgI-SiO_2-Ag结构的三介质层中空玻璃光纤，在中红外波段获得了低损耗特性。SiO2薄膜采用液相涂布法进行涂布，并使用半无机聚合物作为涂布材料。为了在两个SiO（2）膜之间沉积AgI膜，首先通过使用银镜反应方法镀敷银膜。然后进行碘化过程以将银层转变成银碘化物。根据测量的损耗谱中损耗峰的位置，提出了一种计算方法来估算各制作步骤中介质层的膜厚。考虑到材料的分散性和内涂层膜的表面粗糙度，计算和测量的损耗谱之间的良好协议被证明。
We report the transmission characteristics of infrared hollow fiber with multi- AgI and SiO(2) inner-coating layers in the mid-infrared region. A three-dielectric-layer hollow glass fiber with a SiO(2)-AgI-SiO(2)-Ag structure was fabricated and low-loss property was obtained in the mid-infrared region. The SiO(2) films were coated by use of the liquid-phase coating method and a semi-inorganic polymer was used as the coating material. For deposition of the AgI film between the two SiO(2) films, a silver film was first plated by use of the silver mirror reaction method. Then the iodination process was conducted to turn the silver layer into silver iodide. A calculation method was also developed to estimate the film thickness of dielectric layers in each fabrication step according to the position of loss peaks in the measured loss spectra. Good agreement between calculated and measured loss spectra was demonstrated by taking into consideration material dispersion and surface roughness of inner-coating films.
