摘要
本論文中我們將探討利用高分子與向列型液晶結合並參雜偶氮苯分子製作成液晶聚合物並使用雷射光所形成的干涉場，製作出可利用光場來調控的液晶高分子聚合物光柵及觀察出大角度二維（2D）晶體透射光柵的色散狀況。
一維光子晶體以及二維光子晶體的光學性質不同，而二維光子晶體的光學性質比一維光子晶體還好，其散射角度可68度，Spectral resolution可達3.6nm/degree，相較於一維光子晶體的散射角30 度，Spectral resolution為3.06nm/degree還要好。此二維光子晶體擁有良好的光學性質，其製造方法簡單、低花費，也可應用在光譜分析上。

Abstract
In the paper, we will discuss the 2D photonic crystals fabricated by holographic polymer-dispersed liquid crystal technique. A dispersion angle of 68° is observed within continuous spectrum dispersion from 360 to 700 nm at an incident angle of 20° using white light as a probe beam. By changing the angle between the sample normal and the probe beam, the dispersed spectrum can be tuned at a spectral resolution of 3.6 nm per degree.
This two-dimensional photonic crystals with good optical properties, its manufacturing method is simple, low cost, and can be applied in spectroscopic analysis.
