我们将基于拓扑优化技术的设计方法应用于光波导器件。在我们的方法中,在使用拓扑优化方法自动生成设计区域中的折射率分布之后,使用具有一些设计参数的原始几何形状重新定义所获得的结构,并且通过顺序线性编程来优化这些参数。作为数值示例,我们演示了如何将该方法用于 90/spl 度/弯曲和具有任意分束比的 T 分支波导。
We apply a design method based on topology optimization technique to optical waveguide devices. In our approach, after a refractive index profile in a design region is automatically generated using a topology optimization method, the obtained structure is redefined using primitive geometries with some design parameters and those parameters are optimized by a sequential linear programming. As numerical examples, we demonstrate how the method can be used for 90/spl deg/ bends and T-branching waveguides with arbitrary splitting ratio.
