This is the same directional coupler from example7. It is being run as a 2D simulation at y=0. Notice that the coupling distance is 63mm instead of the 37.2mm found in the 3-D model. This should not be surprising given the extreme sensitivity of the coupling distance to waveguide geometry. The 3D model is obviously more accurate here. The 2D simulation is about 30 times faster than the 3D in this example.
