In the thesis, we use R-Soft program to find the appropriate photonic crystal structure which can replace laser cleaved mirror and provide high reflectivity as high as 71% for 980 nm laser. Furthermore, we replace mirror with air bridge mirror in order to prevent light from escaping below photonic crystal. Then we observe whether it can provide higher reflectivity.

本论文利用R-Soft软体来对二维光子晶体做模拟，找出适当的二维光子晶体排列，能对於波长980 nm雷射提供高的反射率，以使光子晶体能取代一般的雷射的劈裂镜面，制作反射率高达71%的雷射镜面，另外，更进一步将镜面改为空桥式镜面，以避免光从有限深光子晶体下方散逸，来研究是否能提供更高的反射率。
