本研究利用Rsoft軟體模擬並整理光纖與光纖間的耦合情況，實驗上使用單模光纖(SMF-28)及抽入甲苯與乙醇混合溶液之空管光纖，使含中空光纖之光纖耦合器只在特定波長耦光，再進一步利用模擬探討會影響耦合能量與半高寬的參數。理論部份從2x2光纖耦合理論出發，實際利用Vytran GPX-3000製作3x3 SMFHOF (單模光纖*1、中空光纖*2)光纖耦合器來驗證不同波長的光耦到不同光纖。在中空光纖甲苯與乙醇混合溶液，使特定波長的光能量耦合到中空光纖達到分光效果，接著比較不同外型的耦合器對耦合能量與半高寬的影響。這種耦合器的優點在於我們能利用流體的特性改變中空光纖的纖核特性，達到調變耦光波長、半高寬的功能。

The purpose of this study is to use multi-functional optical fiber processing platform to produce a fiber coupler composed of solid-core fibers and hollow-core fibers, and utilize theory and simulation to analyze the fused fiber coupler device. The characteristics of this coupler is a fiber coupler in which a single-mode fiber replaced by the hollow-core fiber manufactured by laboratory. The hollow-core fibers were flowed into the mixed solution of toluene and ethanol. The specific wavelength can be coupled to the hollow-core fiber due to the characteristics of the mixed solution. The spectral bandwidth and the coupling power of the fiber coupler composed of solid-core fibers and hollow-core fibers has been analyzed theoretically and demonstrated. The coupling wavelength and spectral bandwidth can be tuned as we changing the characteristics of the hollow core of the fused fiber coupler device.
