為了提昇發光二極體的光萃取效率,本論文提出
兩個新的結構,一為陣列型高反射鏡發光二極體,另
一為具有光子晶體特性之發光二極體。使用嚴格耦合
波分析理論計算氮化鎵發光二極體內鑲嵌微型結構之
光萃取效率與遠場分佈,並探討不同發光二極體結構
之設計對光萃取效率的影響;本論文共分析四種結構,
圖案化藍寶石基板(patterned sapphire substrate)發光二極
體(PSS-LED)、SiO欲圖案化(patterned SiO欲)發光二極體(P-
SiO欲-LED)、陣列型高反射鏡(micro mirror array)發光二極
體(MMA-LED)與陣列型自我複製式光子晶體(auto-cloned
photonic crystal array)發光二極體(APhC-LED)等。根據
我們的理論計算,APhC-LED有最好的光萃取效率,高
達83.4%,相較於一般LED,提昇效率約584%。

In order to enhance light extraction eciency, we pro-
posed two new structures in this paper, micro mirror array and auto-cloned photonic crystal array embedded in GaN.
Light extraction eciency and far eld of GaN-LED with embedded micro-structure were studied using rigorous coupled-wave analysis(RCWA) simulation. Besides, we also investigated the dependence between light extraction efficiency and structural parameters of micro-structure embedded in GaN-LED. Patterned sapphire substrate(PSS)-LED, patterned SiO欲(P-SiO欲)-LED,micro-mirror array(MMA)-LED, auto-cloned photonic crystal array(APhC)-LED were compared in this paper. According to model calculation and analysis, the APhC-LED had the best light extraction eciency, 83.4%, and the enhancement effciency compared with conventional LED was 584%.
