    Abstract: 如何減少光在傳輸耗損是重要的工作,而在界面處之反射是其中之一。本論文主要利用光子晶體層來減少微光學元件界面處的反射,並試著用薄膜理論來驗證模擬結果。第一步,試著把光子晶體在Γ-Μ方向的等效折射率算出。第二步,用第一步驟所算出折射率代入薄膜理論加以比較模擬結果,由模擬結果發現加入光子晶體層,穿透率由原來50.1%提昇到76.2%。第三步,把模擬出最好的光子晶體結構加到光子晶體分光器及光子晶體透鏡,並比較加入前後的差別,以證明光子晶體層的效用。由模擬結果發現加入光子晶體層後分光器的輸出有增加。由原來的0.322(a.u.)增加為0.369(a.u.) 。且光子晶體透鏡加上光子晶體層聚焦點強度確有增加。I try to find a new way to get higher transmission.The anti-reflection of photonic crystal layers is an possible way to increase transmission.I try to change the radius of photonic and number of layers,and hope to get more higher transmission,and applied it on photonic crystal devices.
