在弱引导近似中，我们提出了一种描述弯曲波导中传播的分析，其特征是横向上的可分离轮廓（可以分级）。然后，我们展示了如何使用最近开发的矩阵方法来准确计算此类波导中的弯曲损耗。然后，我们提出了一种新颖的折射率分布，其弯曲损耗可以变得非常小。
In the weakly guiding approximation, we present an analysis describing the propagation in bent waveguides characterized by a separable profile (which may be graded) in the transverse direction. We then show how the recently developed matrix method can be used to calculate accurately the bending loss in such waveguides. We then suggest a novel refractive-index profile for which the bending losses can be made extremely small.
