A Study of the Emission Characteristics of Organic Thin-film Two dimensional Photonic Band-edge Lasers

本論文致力於研究有機薄膜能帶邊緣型光子晶體雷射。在材料的選擇上，我們使用發藍光的小分子，全名2-(4-(pyren-1-yl)phenyl)triphenylene，簡稱PPT，並且搭配有機高分子做為我們的增益材料。我們手邊有三種有機高分子材料，分別為PVK分子量90,000、PVK分子量1,100,000與PC分子量64,000，我們利用自發性激發放大實驗的量測與理論分析去決定PTT參雜在三種高分子材料中的增益特性，進而決定我們的增益材料。決定材料之後，我們將引入光子能帶圖來設計我們的光子晶體結構，並搭配Bragg繞射理論去分析光在光子晶體中的偶合系統。在元件製作上，我們利用電子束微影蝕刻術去達成奈米結構的設計要求。最後我們完成了五種不同的能帶邊緣型的光子晶體雷射去比較與印證分析的理論，並且在光激發光的實驗中我們成功地觀察到雷射放光現象。

This thesis concentrates on the emission characteristics of the thin-film organic 2D-photonic band-edge lasers. The gain material is mostly a blue dye, 2-(4-(pyren-1-yl)phenyl)triphenylene, which is called PPT for short. The organic thin-film is PPT doped in polymer. We have three polymers to select, PVK of M.W. 90,000, PVK of M.W. 1,100,000, and PC of M.W. 64,000. We utilize Amplified Spontaneous Emission (ASE) technique to decide which polymer and weight percent. 2D-photonic crystal lasers with triangular lattice are designed by photonic band diagram and fabricated by electron beam lithography. We design five structures with different band gaps to compare in this thesis.
