摘要註:
本研究採用改良式之雙變曲率光纖端面研磨機進行光纖端面研磨,研磨成橢圓形、雙變曲率形、錐式楔形等幾何圖形。並選用U_15*(〖15〗^7)的均勻設計表,以角度、進給率、迴轉速為控制因子,依序研磨光纖端面,其後經熔燒機熔燒端面去除尖點形成光纖透鏡後,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。並應用克利金插值法分析得到最佳化的參數組合與預期值,經實驗驗證得到以下的研究結果。1. 橢圓形光纖經由均勻設計表實驗完成後其最佳耦合效率為78.6% ,將U_15*(〖15〗^7)所得的數據,再應用克利金插值法分析得到反應曲面而以非線性規劃法找出最佳之參數組合為角度56°,迴轉速289 r.p.m,進給率52 μm/ rev,經實驗驗證,其耦合效率為79.63%,提升了1.03%。2. 雙變曲率形光纖經由均勻設計表實驗完成後其最佳耦合效率為84.58%,將U_15*(〖15〗^7)所得的數據,再應用克利金插值法分析得到反應曲面而以非線性規劃法找出最佳之參數組合為角度55°,迴轉速234 r.p.m,進給率55 μm/ rev,經實驗驗證,其耦合效率為84.92%,提升了0.34%。3. 錐式楔形光纖經由均勻設計表實驗完成後其最佳耦合效率85.12%,將U_15*(〖15〗^7)所得的數據,再應用克利金插值法分析得到反應曲面而以非線性規劃法找出最佳之參數組合為角度54°,迴轉速337 r.p.m,進給率56 μm/ rev,經實驗驗證,其耦合效率為86.38%,提升1.26%。本文主要選用U_15*(〖15〗^7)的均勻設計表並應用克利金插值法找出最佳的光纖耦合效率,並進行實驗驗證,以完成最終品質確認,而以此最佳的加工條件來建立單模光纖耦光效率的技術資訊,以所得之最佳化提供業界參考並建立資料庫。 In this study, we demonstrate the formation of Sui round, bivariate curvature-shaped, cone wedge and other geometric shapes of fiber end face by using a grinding machine with bivariate curvature tooling. Uniform design table of selected U_15*(〖15〗^7) tooling parameters in griding angle, feeding rate, rotation speed are applied to achieve performed end shape of the fiber, and followed by spicing machine to form the lens structure at the fiber end. A measuring system consisted by a 980nm laser diode, and photo-diode was used to measure the coupling efficiency for each type of fiber end, and scanning electron microscopy (SEM) was used to reveal the surface morphology of grinded fiber end. In addition, Kriging interpolation method was applied to sort out the optimized parameters in grinding and verified by experimental results as follows:1. A coupling efficiency of 78.6% for oval-shaped optical fiber has been calculated by applying the uniform design table of U_15*(〖15〗^7), and optimized combination of grinding parameters such as the feeding angle 56 °, rotation speed of 289 rpm, feeding rate 52 μm / rev were derived from Kriging interpolation method using nonlinear rules of law, and 79.63% coupling efficiency with improvement of 1.03% of this type of grinded fiber end was achieved and verified by experimental measurement.2.A coupling efficiency of 84.58% for Bivariate curvature-shaped optical fiber has been calculated by applying the uniform design table of U_15*(〖15〗^7), and optimized combination of grinding parameters such as the feeding angle 55 °, rotation speed of 234 rpm, feeding rate 55 μm / rev were derived from Kriging interpolation method using nonlinear rules of law, and 84.92% coupling efficiency with improvement of 0.34% of this type of grinded fiber end was achieved and verified by experimental measurement.3.A coupling efficiency of 54.12% for Cone wedge-shaped optical fiber has been calculated by applying the uniform design table of U_15*(〖15〗^7), and optimized combination of grinding parameters such as the feeding angle 54 °, rotation speed of 37 rpm, feeding rate 56 μm / rev were derived from Kriging interpolation method using nonlinear rules of law, and 86.38% coupling efficiency with improvement of 1.26% of this type of grinded fiber end was achieved and verified by experimental measurement.We demonstrate that the integration of Uniform design table U_15*(〖15〗^7) and Kriging interpolation method is able to achieve the optimization of the coupling efficiency of the grinded shape of the fiber end with verification by experimental measurements. It is essential in tooling parameters and the data base to optimized the coupling efficiency of the single mode optical fiber.
