    摘要註: 本論文係以改良式之雙曲率光纖端面研磨機來做研究,主要是在探討光纖研磨的角度、進給率、迴轉數等參數條件下研磨出不同端面形狀其對光纖耦光效率之影響,再選用L9(34)的實驗計畫表,以角度、進給率、迴轉速為控制因子,並分別設定三個水準,經由研磨機研磨,並使用電熔燒機燒熔製成光纖透鏡,其後,利用980nm雷射二極體、功率計等量測設備量測其耦光效率的數據,該等光纖透鏡亦利用電子顯微鏡(SEM)觀測其表面形貌。用田口實驗法進行最佳化的分析,繪製回應表與回應圖,而得到光纖端面為四角形、八角形、圓形等最佳研磨之參數組合,其中,四角形光纖耦合效率之最佳參數組合為A2B3C3D3(研磨角度45度、進給率60um、轉速400r.p.m.),八角形光纖耦合效率之最佳參數組合為A2B3C3D3(研磨角度45度、進給率60um、轉速400r.p.m.) ,圓形光纖耦合效率之最佳參數組合為A2B2C3D2(研磨角度45度、進給率50um、轉速300r.p.m.)。再經進行實驗驗證而得到最佳的耦光效率,在四角形耦合效率上從66.82%上升為70.67% ,改善3.85%,在八角形耦合效率上從72.45%上升為74.86% ,改善2.41%,在圓形光纖耦合效率上從77.43%上升為81.91% ,改善4.48%,完成最終品質確認,而以此最佳的加工條件,來建立光纖端面研磨資料庫以提供業界參考。 In this study, end face design optimization for improving optical fiber coupling efficiency with laser diode obtained according to Taguchi method. Grinding mechanism for optical-fiber endface with double variable curvatures was used to fabricate tetragon endfaces, octangle endfaces and circular endfaces of fiber which were arced into fiber microlens. A system for measuring coupling efficiency between laser diode and microlens was set up to investigate the variation of angle, feed rate, revolution of grinding mechanism to the coupling efficiency. In addition, SEM picture of the fiber microlenses surface were provide for verification.The optimal parameters of coupling are determined by Taguchi method and reaction ratio tables and figures, the results of Taguchi method showed that the optimal samples was A2B3C3D3 for the tetragon endfaces, A2B3C3D3 for the octangle endfaces and A2B2C3D2 for the circular endfaces.After achieving the optimal manufacture parameters of fiber microlenses, measuring of coupling efficiency were proceed to verify the results. The coupling efficiency of optimized tetragon microlenses was improved from 66.82% to70.67%. The coupling efficiency of optimized octangle microlenses was improved from 72.45% to 74.86%. The coupling efficiency of optimized circular microlenses was improved from 77.43% to 81.91%. These results of optimized manufacture parameter of fiber microlenses is useful to establish the model of w-powder sinter electrical discharge machining, and to help the development of efficient coupling.
