提出了一种基于折射率分布替代表达式的光波导器件拓扑优化设计方法。在我们的方法中，在设计区域的折射率分布表示的扩展与一些解析函数和灰色区域，这具有可用材料之间的中间折射率，不出现。与目前广泛使用的密度法相比，该方法在波导弯曲和分支的优化设计中可以得到更好的结果。
We propose a design method for optical waveguide devices based on topology optimization with alternative expression of refractive index distribution. In our approach, a refractive index distribution in a design region is expressed by an expansion with some analytical functions and gray area, which has intermediate refractive index between usable materials, does not appear. We can obtain better results in the optimization of waveguide bends and branches, compared with the widely used density method.
