本文将交替方向隐式（ADI）法应用于三维光纤波导的分析。数值结果表明，ADI方法提供了更高的计算效率和更大的传播步长，与传统的光束传播方法，使用快速傅里叶变换。利用透明边界条件计算了耦合偏置光纤的导模传输。
The alternating direction implicit (ADI) method is applied to the analysis of three-dimensional optical fibre waveguides. It is numerically demonstrated that the ADI method offers higher computational efficiency and a larger propagation step length, as compared with the conventional beam propagation method which uses fast Fourier transformation. The guided-mode transmission of coupled offset fibres is calculated using a transparent boundary condition.
