Some Infrared materials - like germanium, silicon (though it is difficult), zinc sulfide, zinc WebFor wavelength from ≈1.8 μm on, the multiphonon absorption leads to steeply rising absorption (infrared absorption edge). Silica can be drawn into fibers at reasonably high temperatures, and has a conveniently broad glass transition (a relatively shallow viscosity curve). Cleaving and fusion splicing of silica fibers works fairly well.
