Abstract

The present work deals with the implementation of algorithms based on the techniques of optimization by ant colony (ACO) and Scatter Search (SS) together with the Finite Element method (MEF) for modeling and optimization of Tapers between a continuous 2D waveguide (CWG) and a periodically segmented 2D waveguide (PSW). The issue to be solved fits into combinatorial optimization problems, where in front of a large number of available subsets, it is possible to select the sets that produce the best coupling efficiencies. The proposed metaheuristics create new possibilities for optimizing and designing a variety of photonic devices for information processing.
