中文摘要 | 本論文提出一新T 型接面光子晶體分光器設計,將傳統T 型接面光子晶體分 光器之分光處結構從彎曲90 度改為45 度的方式並加入一個散射體以改善光傳輸 特性。藉由有限差分時域法模擬分析,結果顯示相較傳統T 型接面光子晶體分光 器,本論文之設計可大幅降低分光器反射率,而使其傳輸率明顯增加,同時元件 工作頻寬也能有效提高。 |
英文摘要 | In this paper, we present a novel T-junction photonic crystal power splitter. Through changing the bending angle from 90 degrees to 45 degrees and inserting a scatterer, we can effectively improve the performance of a conventional T-junction photonic crystal power splitter. The analysis of the T-junction photonic crystal power splitter is performed with the finite-difference time-domain method. And the simulation results show that the proposal design of the paper can greatly reduce the reflection of the structure, resulting in an apparent increase in the transmission of the guiding light, while also effectively broaden the bandwidth compared with the conventional T-junction photonic crystal splitter. |
