聚合物光纤的泛频吸收理论分析

Theoretical Analysis of Overtone Absorption for Polymer Optical Fibers

基于Ｍｏｒｓｅ电势对聚合物光纤（ＰＯＦ）的分子振动吸收进行理论分析，导出确定谐波波数、相对强度及吸收损耗的公式．对ＣＨ，ＣＤ，ＣＦ等进行了具体计算，所得结果和实验符合较好．

Overtone absorption for polymer optical fibers is theoretically analyzed based on Morse potential. Formulas for overtone wave number, relative intensity and absorption loss are derived. Applied to CH,CD,and CF, the results of calculation show good agreement with experiments.
