本論文主要著重於改善熔拉平台(FCMW-2000)內部參數設定以利於研製出高品質、高通道隔離係數之波長分波多工器。實驗使用熔燒耦合技術，將兩根剝除被覆(coating)的光纖藉由熔燒的高溫加以延伸，逐步改變光纖結構，因模態場直徑(mode field diameter, MFD)的重疊造成能量耦合，最後達到適當的耦合比。實驗分兩部分:光通訊光纖(SMF-28)之1590/1950nm波長分波多工器的改良以及研製使用HI980光纖之918/976nm波長分波多工器，實驗以熔拉光通訊光纖(SMF-130V)為基礎，逐步改良熔拉遇到的非理想效應達到高品質與高通道隔離度的分波多工器，累積經驗後再進階的使用HI980光纖完成理想耦合比的分波多工器，最佳化所有參數後，得到穩定且高品質的波長分波多工器的製作設定。本論文簡易介紹波長分波多工器的機制，以完整的實驗數據來討論如何研製出理想的元件。

The purpose of this thesis is to fabricate a high-quality WDM (wavelength division multiplexing) dividing the wavelengths of 918 and 976 nm. All-fiber based coupling WDM mainly coordinates with the all-fiber laser system and properties of low cost, low loss, high isolation, simple production and so on. Because of the closer wavelengths, the difference of two wavelengths propagation constants are small and need to reach the coupling difference of half cycle about at the 7th and the 8th cycle. The experiment will improve the coupling performance of old setting up 1590/1950 WDM, and then use the experience of optimizing to produce the theme of this paper 918/976 WDM.Using fused biconical taper (FBT) fabricates WDM, and two fibers are parallel and closely. When two waveguides are closely to each other, energy starts coupling and jumping in the two waveguides. In the optimization of the old setting up, the optimal parameters of torch height and pulling factors are obtained, which are in accordance with the expectation in some papers. For the 980 and 976 nm wavelengths WDM progressive optimization parameters set to find the most successful production methods. Finally finished samples package in glass tube to complete the specific wavelength 918 and 976 wavelength division multiplexing WDM components.
