本國際合作計畫(國立中央大學與美國德州大學阿靈頓分校)主要目的為開發可分析以光子晶體結構為基礎而設計之光學元件的電腦輔助工具(computer aided tool) ，為一規畫三年之計畫，第一年計畫正執行中。計畫由中央大學陳念偉博士與美國德州大學阿靈頓分校陸明宇(Mingyu Lu)博士與周緯東 (Weidong Zhou)博士共同執行。中央大學主要負責電腦輔助設計工具之開發，德州大學主要負責光學元件之設計與製作及電腦輔助設計工具之驗證。在電腦輔助設計工具開發方面，中央大學將建立有效率及準確之時域(time-domain)與頻域(frequency-domain)電磁全波解答器(electromagnetic full-wave solver)。時域解答器建立上，將採用時域有限差分法(finite-difference time-domain)，並透過平行化(parallelization) 方式提昇效率; 而頻域解答器將採用週期矩量法 (periodic method of moments) ，透過快速多偶極演算法(fast multipole method) 及週期格忍函數(periodic Green’s function)計算平行化提昇效率。目前已完成頻域解答器與時域有限差分法之建立與元件量測驗證，正進行演算法之平行化。所開發之電腦輔助工具將用於研製與改良光學元件，光學元件之設計與製作將於德州大學波散射研究中心(Wave Scattering Research Center)及奈米科技研究與教學中心(Nanotechnology Research and Teaching Facilities, NanoFAB)完成。 ; The proposed international collaborative three-year research aims at developing novel computer aided design (CAD) tools for photonic crystal-based optical devices. The first-year research is currently conducted by Dr. Nan-Wei Chen with the National Central University (NCU), Taiwan and Dr. Mingyu Lu and Dr. Weidong Zhou with the University of Texas at Arlington (UTA), USA. The major part of the proposed research, including the development of the design tools, will be carried out in NCU, Taiwan. The developed CAD tools will be verified and tested in UTA. Specifically, the accurate time-domain (TD) as well as frequency-domain (FD) -CAD tools based on electromagnetic full-wave solvers and pertinent to the analysis of the photonic crystal structures have been developed and verified in the first quarter of the first-year research. Currently, the parallel acceleration for both FD and TD solvers proposed predominately for efficiency improvement on the classical FDTD are under development. Experimental study of photonic crystal devices are currently conducted at the Wave Scattering Research Center (WSRC) and the Nanotechnology Research and Teaching Facility (NanoFAB) in UTA, and the experimental data will be used to verify the design tools. The developed CAD tools are expected to be successful aids for the design of photonic crystal devices. ; 研究期間 9708 ~ 9807
