Paper Abstract

We present a novel Memetic optimization algorithm (MA) in conjunction with the frequency domain Finite Element Method (FEM) to design and to optimize 90° bend waveguide. Transmission efficiencies greater than 98% have been achieved for the desired operating wavelength. by using the proposed strategy, opening, new possibilities for photonic devices design and configurations. In the proposed approach, several geometrical conditions and restrictions were considered and imposed on the bending region in order to reduce the bending footprint. Compared with conventional bending schemes, our solution exhibit good fabrication error tolerances and higher transmission efficiency.
