We present the use of the Douglas-Gunn Alternating Direction Implicit finite difference method for computationally efficient simulation of the electric field propagation through a wide variety of optical fiber geometries. The method can accommodate refractive index profiles of arbitrary shape and is implemented in a tool called BPM-Matlab. We validate BPM-Matlab by comparing it to published experimental, numerical, and theoretical data and to commercially available state-of-the-art software. It is user-friendly, fast, and is available open-source. BPM-Matlab has a broad scope of applications in modeling a variety of optical fibers for diverse fields such as imaging, communication, material processing, and remote sensing.
我们展示了使用道格拉斯 - 冈恩交替方向隐式有限差分方法，对电场通过各种光纤几何结构的传播进行高效计算模拟。该方法可以适应任意形状的折射率分布，并在一个名为BPM - Matlab的工具中实现。我们通过将BPM - Matlab与已发表的实验、数值和理论数据以及市售的先进软件进行比较来验证它。它用户友好、速度快且开源。BPM - Matlab在为成像、通信、材料加工和遥感等不同领域的各种光纤建模方面具有广泛的应用范围。
