N2 - Two recent extensions of the coupled mode theory to non-parallel waveguide systems are examine here, qualitatively and numerically. It is shown that whereas the basic formulation, when applied to non-parallel systems, is reasonable for describing coupling between nearly parallel waveguides, these two extended formulations may be incompatible for non-parallel guides, on physical grounds.
