| 摘 要： | 通过对于光纤断裂机理的分析,确认了目前影响保偏光纤的断裂两种形式,发现了不同于常规“延展性断裂”的“脆性断裂”,通过对于断裂形式的分析及研究,明确了“延展性断裂”与“脆性断裂”的差异,最终通过实验得到了“脆性断裂”产生原因及表现形式,对于保偏光纤应用过程中的机械损伤控制起到了指导作用。

| Abstract: | Through the analysis of the fracture mechanism of optical fibers,the current fracture modes affecting polarization maintaining optical fibers are confirmed,and the "brittle fracture" which is different from the conventional "ductile fracture" is found out.Finally through the analysis and study of the fracture modes,the difference between "ductile fracture" and "brittle fracture" have been made clear.The causes and manifestations of brittle fracture are obtained through experiments,which play a guiding role in the mechanical damage control of polarization maintaining optical fibers. |
