    • 全漏光導模量測系統已架設完成，並可用於實際之量測應用，但為了驗證全漏光導模系統的穩定性與正確性，我們先量測結構較為單純的零階半波板，並分析其實驗結果，希望透過實驗結果與模擬結果的擬合，檢視系統目前實際的可靠度。為了提升擬合的效率，我們也使用了基因演算法來執行擬合的工作，以貝立曼 4x4 矩陣為基礎的異向性材料的光學模擬也應用於樣本模型的建立。

    We have finished the installation of fully leaky guided mode (FLGM) system that is ready for experimental measurement. In order to evaluate stability and reliability of FLGM system, wemeasure optical signals with a zero order wave plate, and analyze experimental results to get physical parameters of zero order wave plate by means of comparison between experiments and simulation. Simultaneously, we also use the more efficient genetic algorithm to fit both experimental and simulated data. Optical simulation for anisotropic materials based on
    Berreman’s 4x4 matrix is also considered.
