摘　　要：对熔锥型光纤耦合器进行了扭转响应研究 通过放置在耦合器一端的旋转装置对未封装的熔锥型光纤耦合器耦合区施加扭转作用 实验表明 :耦合器的耦合比不但对扭转作用敏感 ,而且变化呈单调性 ;同时耦合器的附加损耗和工作波长不受扭转作用影响 ,并且这种扭转操作具有可重复性 通过扭转操作能够对生产出来偏离预定耦合比的耦合器进行调整 ,使之符合产品要求 。The strain response of fused tapered fiber coupler is studied.The axial twisting of a fused tapered fiber coupler without being packed through the rotating device placed at the either and of the coupler causes the coupling ratio of the coupler varies across all possible values.The experiment results indicate that not only the coupling ratio of the coupler is sensitive to twist,but also the changing is monotone;at the same time the coupler loss and the working wavelength suffered no significant change at any stage,and demonstrate the reproducibility of the twisting effect.The fused tapered coupler whose coupling ratio doesn′t fit in with the needs can satisfy the manufacture demands through adjusting it by twisting the coupling zone.Thus,this method can increase the production efficiency.
