光纤端面透镜微磨削加工角度试验研究

Experimental Study on the Micro Optical Fiber End Face Lens Grinding Angle

光纤端面透镜是重要的耦合器件之一,而光纤端面透镜的形状是影响光纤耦合的主要原因。文章在分析传统光纤透镜传统加工技术的基础上,提出了用微磨削加工光纤透镜的方法。并着重对光纤在磨削过程中角度的变形进行研究。该试验利用125μm的单模光纤进行磨削实验,通过力学分析光纤在加工过程中进给速度、主轴转数、悬伸长度等因素对光纤加工角度的影响。试验结果表明使用微磨削加工光纤端面透镜,在一定范围内光纤的悬伸长度、进给速度与角度成正相关关系,主轴速度与光纤角度成负相关关系。

Optical fiber end face lens is one of the important coupling, and the optical fiber end face of the shape of the lens is the main factor affecting the optical fiber coupling. So based on the analysis of the tradi-tional optical fiber lens, on the basis of traditional processing technology, it presents the method of micro grinding fiber lens. And of optical fiber in the process of grinding Angle deformation were studied. This ex-periment using 125 μm of single-mode fiber grinding experiment, through the mechanical analysis of optical fiber in the machining process, related to those factors, and mainly for：feed speed and spindle revolutions, overhanging length and other factors on the fiber processing point of view. Experimental results show that this method is used to meet the machining requirements, and within a certain range the overhanging of the fi-ber length, Angle and feed speed into a negative relationship, feed rate are positively correlated with fiber optic Angle.
