The characteristic interactions of discrete modes supported by planar isotropic and anisotropic dielectric slab waveguides are analyzed using singularity and critical point theory, leading to a rigorous and complete explanation of all modal interactions. Complex frequency-plane singularities associated with modes on isotropic waveguides are identified andâ€¦Â (More)
