Summary We consider a waveguide with principal guiding direction for which the beam propagation method is applicable. A simulation method based on an FEM for Maxwell's equation with 3D Nedelec elements is developed. The power loss of the waveguide is minimized by varying a finite number of shape parameters. We validate the method by comparing our findings to some published results. Copyright © 2014 John Wiley & Sons, Ltd.
