Abstract

The work in this paper is based on a powerful function-fmincon in matlab and Finite Element Method, optimizing the shape and the position of dielectric rods surrounding the termination of a photonic crystal waveguide, in order to increase the directional emission. The method is simple, but can lead to useful results efficiently. More than fivefold improvement in power incident upon a target area over a simple termination is achieved, and the optimized structure is easier for fabrication.
