光子晶體是一種不同折射率材料呈週期性排列的光學介質結構,經由模擬設計,可以實現調控電磁波的傳導來符合需求。在本篇論文中,共研究了兩個主題。 第一個是利用轉移矩陣法(TMM)來設計出以矽為基板的抗反射層(ARC),此ARC主要的波段為可見光到紅外線的範圍,力圖將反射率降至最低,提升整體的效率。經由不同的角度來觀察 TE、TM模式下的反射光譜。 第二個主題是利用金屬與介電質材料來設計出光學量子井(PQW)結構,我們分析銀、鋁、銅這三種金屬是否皆具有量子井的特性,結構上都以反對稱結構(AB)^m(MC)^n(AB)^m 為主,A=B=C=介電質,M=金屬,量子井的特性是可做為多通道的濾波器,可藉由調控缺陷的週期來實現,並在最後的分析找出濾波器的工作頻段。
