Paper Abstract

A rigorous analysis of two-dimensional segmented waveguide (2D-SWG) crossing using evolutionary algorithms in conjunction with the two-dimensional finite element method (2D-FEM) is presented. The power transmission and crosstalk of the waveguide crossings are calculated, optimized and compared with other designs in the literature. The optimized crossing has been successfully and efficient designed using evolutionary algorithms based on genetic algorithm (GA). Power transmissions above 90 % and crosstalk below 40 dB over a broadband interval of wavelength have been obtained with the evolutionary algorithm.
