在弱引导近似下，我们提出了一个分析，描述了在弯曲波导的传播，其特征在于一个可分离的配置文件（这可能是渐变的）在横向方向。然后，我们展示了如何最近开发的矩阵方法可以用来准确地计算在这种波导的弯曲损耗。然后，我们提出了一种新的折射率分布的弯曲损耗可以非常小。
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.
