摘　　要：光纤拉锥是光纤器件制作中的一项重要技术,为了研究快速往复移动温区熔融拉锥系统中锥区形貌与各拉锥参数的关系,基于体积不变原理,建立了往复运动温区熔融拉锥系统在满足温区运动速度大于光纤拉伸速度条件下的理论模型,详细描绘锥区形貌形成过程,推导出锥区直径、锥区平坦区长度与温区运动次数、温区运动速度、光纤拉伸速度、温区往复运动距离以及温区宽度与光纤初始直径之间的定量关系,并进行验证,实验结果与理论分析一致。Fiber taper is an important technology in optical fiber device manufacture.In order to research the relationship between the taper wasit shape and the taper parameters in the fast reciprocating moving hot-zone fused taper system,a theoretical model of the reciprocating moving hot-zone fused taper system is established based on the principle of volume invariance under the condition that the hot-zone moving speed is greater than the fiber tapering speed.The deformation processing of the tapered optical fiber is depicted in detail.Quantitative relationships between the diameter of the taper waist,the length of the taper waist and the moving number of the hot-zone,the moving speed of the hot-zone,tapering speed of the fiber,the reciprocating moving distance of the hot-zone,the width of the hot-zone and the initial optical fiber diameter are deduced in this paper.Experiments are also carried out to verify the validity of the proposed theory and the experimental results have good agreement with the theory.
