摘要

基于CO

熔拉锥技术

对熔拉锥设备的控制方法进行了改进。利用柱体Mie散射公式计算光纤在加工过程中的光能利用率

结合Grellier的热传导模型

确定了加工过程中激光功率增长与光纤拉伸距离之间的对应关系。利用计算结果

采用分段直线递增的方法对激光功率进行控制

简化了仪器控制的难度。实验得到锥腰直径2~3 μm左右的熔锥光纤

锥腰和过渡区的形状和尺寸都得到了很好的控制。

Abstract

Based on CO

laser fabrication of fused-fiber taper rig developed by E. D. Timothy in 1999

a shorter focused lens was used to improve the laser power controlling in the paper. The Mie theory of cylindrical structures and the heat transfer modeling proposed by A.J.C. Grellier was used to derive the increment relation of the laser power with the drawbench distance. The relation was in section increase linearly by degrees for laser power controlling

which simplifies the computer control of the rig. The fused biconical-tapered fibers with 2~3 μm diameter in the waist were obtained in the experi ment

it indicates the size and shape of biconical-tapered fiber is consistent with the predicted one well.
