本篇論文將探討環形共振器的設計和製作，由於它的波長選擇性，使得在積體光電子學上有廣泛的應用。在本文中，特別之處在於利用硬脂酸作為交換源，藉此在鈮酸鋰基板上使用質子交換法，製作一個半徑為數百微米的雙環並聯環形共振腔。之後使用光束分析儀去觀察分析共振腔的光分布模態，以及利用紅外光感測器連結至光學電表去量測評估其傳輸功率大小，接著通過錐形透鏡光纖將光源耦合進輸入波導之中，使用波段為C+L頻帶的放大自發放射 (Amplified Spontaneous emission) 光源，在共振條件下，對光源進行選擇性的篩選，並在輸出端處量測到所對應的傳輸頻譜。最後發現雙環並聯環形共振腔的特性結果與預期結果有些差異，並分析探討後續的失敗原因。

This thesis focuses on investigating the design and fabrication of microring resonators (MRR). Because of their unique sensitivity in wavelength, they have found a wide applicability in integrated optoelectronics. Specifically, parallel dual microring resonators with radii of hundreds of microns are fabricated in lithium niobate (LiNbO3) substrate using stearic acid as a proton exchange source. These resonators are first analyzed by observing their mode profiles using a beam profiler and transmission power amplitudes are evaluated using the infrared photodetectors coupled with an optical multimeter. Then, the aforementioned devices are then spectrally characterized by focusing C+L-band ASE light source into the bus waveguide via a tapered lensed fiber and under a selective resonance condition, the corresponding transmission spectrum can be duly extracted from the through port. Finally, a subsequent failure analysis is also performed in order to speculate why the performance of dual MRRs deviated from the initial expectation.
