    • 本論文的目的是研究層狀結構的光學性能的基礎上使用漸逝波。被認為是三種結構。首先，我們探討共振隧穿介電介質光子晶體（DDPC）。 DDPC在此，我們將介紹一個從高至低的界面的入射角大於臨界角的漸逝波。結果表明，這樣的有限DDPC可以用來設計一個多通道的發送濾波器。第二，我們繼續研究這也是另一個過濾器結構倏逝波的使用操作。該過濾器是特別適用於偏振依賴性的光學裝置。事實上，它是一種多通道的雙偏振帶通濾波器。第三，我們使用受抑全內反射（FTIR）來設計的50/50分束器。高折射率玻璃的色散關係，包括在我們的研究中。這種分離器的臨界條件已經顯露出來。

    The purpose of this thesis is to study the optical properties of layered structures based on the use of evanescent waves. Three structures are considered. First, we investigate resonant tunneling in a dielectric-dielectric photonic crystal (DDPC). In this DDPC, we introduce an evanescent wave from the high-to-low interface at an incidence angle larger than the critical angle. The results indicate that this finite DDPC can be used to design a multichannel transmission filter. Second, we continue to study another filter structure which is also operated with the use of evanescent wave. This filter is of particular use in the polarization-dependent optical device. In fact, it is a multichannel double-polarization band pass filter. Third, we use the frustrated total internal reflection (FTIR) to design a 50/50 beam splitter. The dispersion relation for the high-index glass is included in our study. The critical conditions for this splitter have been revealed.
