摘要

本篇論文，我們提出利用二維光子晶體Mach-Zehnder干涉儀來儲存光能量。所研究的Mach-Zehnder干涉儀是由光子晶體分光器、波導與轉角波導(arm)所構成並利用有限時域差分法(FDTD)來模擬光場與能量分佈。為了能夠儲存能量，我們改變光子晶體Mach-Zehnder干涉儀中部分區域的折射率讓相位差可以產生變化，進一步地使Q值可以自由地操控。目前能量儲存的模擬結果，其Q值大小約為1482。

In this study, we propose a way to store power of light using a two-dimensional photonic crystal Mach-Zehnder interferometer. The Mach-Zehnder interferometer composed of photonic crystal channel waveguides、beam splitters and arms is simulated by 2-D finite-difference time-domain(FDTD). Using the change of the index of dielectric rods in the photonic crystal arm alters the phase difference to control quality factor (Q factor) of the Mach-Zehnder interferometer structure dynamically. We obtain Q factor = 1482 for the Mach-Zehnder interferometer structure at present.
