A finite-element-based vectorial optical mode solver is used to analyze microstructured optical waveguides. By employing 1st-order Bayliss-Gunzburger-Turkel-like transparent boundary conditions, both the real and imaginary part of the modal indices can be calculated in a relatively small computational domain. Results for waveguides with either circular or non-circular microstructured holes, solid- or air-core will be presented, including the silica-air Bragg fiber recently demonstrated by Vienne et al. (Post-deadline Paper PDP25, OFC 2004). The results of solid-core structures are in good agreement with the results of other methods while the results of air-core structure agree to the experimental results.
一种基于有限元的矢量光学模式求解器用于分析微结构光波导。通过采用一阶类似贝利斯 - 冈兹伯格 - 图克尔的透明边界条件，可以在相对较小的计算域中计算模态折射率的实部和虚部。将给出具有圆形或非圆形微结构孔、实心或空心的光波导的结果，包括维耶纳等人最近展示的二氧化硅 - 空气布拉格光纤（截止日期后论文PDP25，2004年光纤通信会议）。实心结构的结果与其他方法的结果吻合良好，而空心结构的结果与实验结果相符。
