This paper deals with the optimization of photonic structures, specifically waveguide couplers between a continuous waveguide (CWG) and a periodically segmented waveguide (PSW). For this purpose, a numerical technique called finite element method (FEM) is used in conjunction with an adapted optimization technique called Scatter Search (SS). In this work the possibilities of finding high coupling efficiencies are extended through the creation of adaptations to the Scatter Search algorithm and the enormous amount of solutions generated to be evaluated by such procedure. The results have showed that the adaptation of the technique is valid for optimization of tapers.

通过散点搜索元启发式逆向设计锥度

本文涉及光子结构的优化，特别是连续波导 (CWG) 和周期性分段波导 (PSW) 之间的波导耦合器。为此，将称为有限元法 (FEM) 的数值技术与称为散点搜索 (SS) 的自适应优化技术结合使用。在这项工作中，通过创建对 Scatter Search 算法的适应以及由此类程序评估生成的大量解决方案，扩展了寻找高耦合效率的可能性。结果表明，该技术的适应对于锥度的优化是有效的。
