Abstract :
A model for optimization of orthogonal bend waveguide has been introduced and investigated. In this study, the connection zone of two orthogonal straight waveguides has been divided into small parts making their refractive indices changeable. The appropriate refractive index has been proposed using Genetic Algorithm (GA) searching. The designed structure has lowest bend loss. Thus, a discrete structure with small bend loss has been suggested for the connection zone of the orthogonal waveguides. The light propagation has been analyzed by Finite Element (FE) method in the connection zone.
