“…However, for non-identical cores, they are not symmetric and therefore, when using conventional CMEs, total power is not conserved. In this case, using the cross-power term, C mn = C nm , the relation between κ mn and κ nm is rewritten as [7,8] nm mn mn mn…”

“…This may produce significant propagation loss [119,120]. It has been demonstrated, at X = 632 nm, that undoped, nonconductive polyanilene, has a dielectric constant £ = 8.47 + 1.14i and conductive, HC1 doped polyanilene has a dielectric constant e = 13.4 + 2.85i [120].…”

“…The coupled mode is approximated by a weighted sum of the modes that exist on the isolated structures. However, these methods are only valid for large separations or well-confined modes [8]. Furthermore, coupled mode theory does not work well for asymmetrical guides [8].…”

“…However, these methods are only valid for large separations or well-confined modes [8]. Furthermore, coupled mode theory does not work well for asymmetrical guides [8]. Marcuse [9] presented a technique for the solution of compound slab waveguides with width and permittivity asymmetry.…”
