【摘要】 给出了作为波导半径函数的弯曲损耗，讨论了小透光孔径波导的优越性，提出了射频（ＲＦ）溅射镀膜的一种新方法，然后用这种方法作成长度相同、导光孔径不同的几个样品，最后测定了几个样品的光透射率，并对其进行了分析比较。更多还原

【Abstract】 The bending loss in Ge--Ag--Ni waveguide as a function of waveguide radius is disscussed. The advantages of the small--sectional radius waveguide are discribed, and a novel method of RF sputterins for fabrication of hollow waveguides with small diameters is proposed. Finally, some samples have been fabricated using the method and the transmitunces of the samples with different waveguide diameters are presented and compared.更多还原
