dc.description.abstract摘要 光纖用於長距離通訊,通常用高功率的980nm LD當光源,搭配參鉺放大器來放大信號。但由於光纖和LD模態的不匹配,造成光進入光纖端面時會有很大的功率損失。 本篇論文利用楔形光纖來改善耦合功率損失,從光纖研磨、及不同的LD模態比和不同的研磨角度對耦合效率的影響、到容忍度的探討,並用實驗及模擬印證,最後成功地利用田氏法來對準,達到快速滿意且優於傳統方法的結果。zh_TW
dc.description.abstractAbstract Efficient Erbium-Doped Fiber Amplifier (EDFA) pumping usually uses semiconductor lasers operating at 980-nm wavelength for long haul light wave communications. But at 980-nm pumping, there’s a problem in the mode field mismatch between the elliptical laser mode and the symmetrically circular fiber mode. Up to date, there are some arrangements for getting higher coupling efficiency, but presented in this study, we used a well-designed wedge shaped fiber with an approximated cylindrical end-face to achieve a high coupling efficiency. Automation of fiber to optic alignment is a critical fiber-optic component manufacturing technology. The key point to the alignment automation is alignment tolerance. For this paper, axial and angular alignment tolerances would be discussed in detail. The “Taguchi Method”, popular and practical in Japan, was effectively utilized to achieve a high coupling efficiency during the alignment experiments.en_US
