Generally speaking, there are two types of optical fibers for Mid-infrared laser transmission. One is solid-core optical fiber and the other is hollow waveguide.

目前研究传输红外激光光纤一般分为两类：红外实芯光纤和红外空芯波导。

Microstructured fibers made of silica undergo high loss in transmission due to the intrinsic material absorption in mid-infrared region.

由于强的红外吸收，石英玻璃材料拉制成的光纤或微结构光纤在中红外波段的传输损耗很大。

Selenide glasses have low material dispersion, high-energy bandgap, long-wavelength multiphonon edge and it's the perfect candidate for mid-far-infrared fibers.

硒化物玻璃具有低的材料色散、高的禁带宽度、长的多声子吸收边，是制备中远红外光纤的优秀材料。
