中文摘要
本研究目的是先利用可調式直徑光纖熔接帄台研製纖衣從
125μm 至 50μm、125μm 至 40μm 錐度不同的單模光纖,利用製程參數中設計不同錐度模型和熔區火力參數搭配,可達到最低損耗 0.77dB,之後在大孔徑石英毛細管內塞入 n 根光纖之後改變錐度製成n×1 光纖組合器,透過設計錐度模型和調整火力參數降低 n 根光纖的傳輸損耗和縮小光纖的直徑達到集中功率效果。
從初步大孔徑石英毛細管的抽製,進一步的到光纖組合器的設計與製作與使用大直徑光纖熔接帄台抽製的過程;其中於製程中欲克服的種種問題,例如:大孔徑石英毛細管選擇、如何固定 n 根光纖塞管後位置、光纖組合器錐度均勻程度、光纖組合器損耗等,皆是目前製作技術上待克服的問題。我們將會探討從製程參數的調整、切割參數
的調整、可調式直徑光纖熔接帄台硬體的改良著手進行改良,其研製7×1 單模光纖組合器損耗約 1.5dB 而 7×1 多模光纖組合器損耗約1.4dB。
7×7 光纖耦合器方面,改變了內裝光纖使得初步功率耦合有了明顯效果,未來達到傳輸功\\\\\\\\率、功率耦合、多波分工的效果。
Abstract
Purpose of this study is to use adjustable platform for development of fiber diameter and fiber fusion from 125μm to 50μm,125μm to 40μm different taper single-mode fiber, the use of different process parameters in the design of fire taper models and parameters with the molten zone, the minimum loss of 0.77dB.After the large diameter quartz capillary
tube inserted into some optical fiber taper changes made after the n×1 optical combiner, and adjusted through the design taper model parameters
reduce the firepower some fiber transmission loss.
In recent years, the application of high-power fiber laser in various industries is widely spreading and exploring. Within the system, one of critical component is the fiber pump combiner. We are currently investigating the fabrication of 7x1 Combiner with both single mode and multimode fibers and the characterization of combiner efficiency as a
function of processing. The development of 7×1 single-mode fiber combiner loss of about 1.5dB and 7 × 1 multimode fiber combiner loss of about 1.4dB
