研究了Ge-Se二元硫系玻璃光纤的散射损耗特性。研究发现，与波长无关的散射损耗与H2O杂质引起的吸收之间存在很强的相关性。因此，H2O杂质的量主要决定这些光纤的波长无关损耗。在去除H_2O杂质和调整制备条件后，在2 ~ 8.5 μm的红外波段，除4.5 μm处有一个小的透射峰外，透射损耗均小于1dB/m。
Scattering loss characteristics of Ge‐Se binary chalcogenide glass optical fibers are investigated. It is found that there is a strong correlation between the wavelength‐independent scattering loss and the absorption caused by H2O impurities. Therefore, the amount of H2O impurity mainly determines the wavelength‐independent loss of these optical fibers. After removing the H2O impurity and adjusting the fabrication conditions, the transmission loss is less than 1 dB/m over a wide infrared wavelength region of 2–8.5 μm, except for a small peak at 4.5 μm.
