Non-Degenerate Surface-Wave Mode Coupling of a System of Dielectric Waveguides,
Abstract
A number of different methods in the literature for calculating the coupling between surface wave modes on parallel optical waveguides are examined and found to give identical results only for degenerate modes. A new variational derivation of the coupling coefficients is given, which is extended in a straightforward manner to include anisotropic guides and/or an arbitrary number of guides or modes. The character of the differences between the various methods in the non-degenerate case is discussed, and the approximations required are investigated numerically for the case of two parallel slab waveguides.
