Consider the symmetric guide first, where the intersection between the solid and the dotted curve yields the zig-zag angle 0 of the fundamental mode.

Abstract. We analyse theoretically for the first time to our knowledge the perfect phase matching of guided TE and TM modes with a multilayer waveguide composed of linear isotropic dielectric materials. Alongside strict investigation into dispersion relations for multilayer systems, we give an explicit qualitative explanation

6 Sep 2005 This dielectric slab waveguide eliminates the metallic absorption loss. We could use the concept of computing Ez or Hz and then applying Maxwell's equations to obtain the remaining field components just .. Each solution involves a guidance equation and a dispersion equation. These equations are:.
Modes (f) and (g), having sinusoidal core-field variation with ? 1 zero-crossings, are common to both dielectric and plasmonic waveguides. This rich variety of modes arises out of the solutions of the dispersion equation written for an asymmetric three-layer slab waveguide. In principle, a single dispersion equation can com-.
