摘要

为从理论和试验两个方面解决光纤端面制备问题

根据固体断裂力学原理

分析和讨论了脆性均匀固体物质的断裂过程

得到了圆柱形物质在某一点的断裂路径具有在裂纹发展方向上的稳定性和唯一性的结论

并据此提出了一种简便的制备光纤端面的设想。根据该设想

设计了一个光纤切割装置并进行了光纤端面制备的试验。在试验过程中

分别对光纤芯径为0.2

0.3

0.6

0.8

1 mm的光纤端面进行了切割

并应用读数显微镜和可见激光传输光束显示等技术手段测试了制备的光纤端面的光学质量。实验结果显示

制备的光纤端面质量完全满足实际应用的要求

质量完好的概率达到100%。

Abstract

To study and fabricate the fiber terminal-faces in both theory and experiment

the fracture principle of a brittle uniform solid material is analyzed and discussed concretely according to the solid fracture mechanics. It is concluded that the fracture route in a point of the columniform uniform solid material has the characteristics of stability and uniqueness in spreading trends. A simple fabricating method to cut the optical fiber terminal-faces is proposed

and an experiment device based on the method is developed. During the cutting experiments

the optical fiber terminal-faces are fabricated with different diameters of 0.2 mm

0.3 mm

0.6 mm

0.8 mm and 1 mm. Then

a reading-microscope and visible laser transmission methods are adopted to measure the optical quality of the obtained fiber terminal-faces. The testing results show that the fiber terminal-faces fabricated by this method can well satisfy the practical application requirements and the probability of high quality for these fiber terminal-faces has reached 100%.
