Abstract
We propose a facilitating model for optimization of waveguide crossing using particle swarm adapted method in conjunction with 2D finite elements to discover geometric configurations associated with the best transmission efficiency values. From a base structure, it was possible to generate optimal solutions by changing the geometric parameters of the initial structure. The change in the geometric characteristics of the structure could provide an enhancement of power transmission. The results of the simulations are presented and discussed to evaluate the performance of the proposed approach. We obtained efficiency values above 95%, showing that the chosen methodologies can be applied with great flexibility for other projects in the field of photonics. In addition, it is also possible to carry out projects with a greater number of waveguides.
