Abstract—

For a multimode optical fiber, whose core is formed by quartz glass of the KU-1 type with a high content of hydroxyl groups, the dynamics of the reversible (recoverable) change in the optical absorption of these groups near 7200 cm^–1 when the light guide is heated to 1050°C, are studied. Based on the decomposition of the absorption band into spectral components at different temperatures, assumptions are made regarding the structure of absorption centers related to the OH groups.

芯部含有高浓度羟基的光纤光导中 7200 cm-1 吸收带的热诱导可逆变化

摘要-对于芯部由羟基含量较高的 KU-1 型石英玻璃构成的多模光纤，研究了当导光体加热到 1050°C 时，这些羟基在 7200 cm-1 附近的光吸收发生可逆（可恢复）变化的动态。根据吸收带在不同温度下分解成的光谱成分，对与羟基有关的吸收中心结构进行了假设。
