摘要: 本研究探討創新結構雙抗諧振反射光波導(ARROW)感測器的設計、製造與特性量測。對於一個抗諧振反射光波導結構而言,光場藉由在包覆層之間的抗諧振反射與空氣-導光層界面的全反射,將光侷限於核心層。抗諧振反射光波導結構可將光導引在較低的折射率,並可靈活地設計核心層的折射率與大小使與單模光纖相容。對於雙抗諧振反射光波導而言,則可以藉由控制最大耦合效率來製作一個定向耦合器,或兩個分離的光波導。基於抗諧振反射光波導結構,沒有任何彎折結構的矽基感測器可以被實現。我們利用轉移矩陣法(TMM)與等效折射係數法(EIM)來分析與設計抗諧振反射光波導結構。然後,我們用波束傳輸方法(BPM)來模擬雙抗諧振反射光波導傳感器的傳播特性。我們製作元件並量測特性。測量結果顯示,沒有彎折結構的矽基感測器是可以被實現的。
The design, fabrication, and characterization of novel Si-based sensors based on dual antiresonant reflecting optical waveguides (ARROWs) are proposed. For an ARROW structure, the light is confined within the core layer by antiresonant reflection in the cladding layers and by total internal reflection at the air-core interface. It can guide lightwaves in low-index cores on a high-index substrate, and the refractive index and size of the cores can be flexibly designed to be compatible with single-mode fibers. For dual ARROW, it can operate as a directional coupler or as two decoupled waveguides by controlling maximum coupling efficiency. Based on these structure, Si-based sensors based on dual ARROWs structure without any bending structure can be realized. The characteristics of dual ARROW structures were analyzed with the transfer matrix method (TMM) and the effective index method (EIM). Then, we used the beam propagation method (BPM) to simulate the propagation characteristics of the dual ARROW sensor. The devices were fabricated and characterized. Experimental results show that our Si-based sensors based on dual ARROW structure without any bending structure can be realized.
