Abstract :
A method is presented for the analysis of waveguide structures with abrupt index changes in both the transverse and axial directions. The method accurately includes the reflected fields and the Goos-Hanchen shift. The method can be extended to three-dimensional and graded index structures, and to include diffraction effects. For a graded index structure with no abrupt index changes the method reduces to the standard beam propagation method
