“…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…”

Coupled-mode and coupled-power theories are described for multi-core fiber design and analysis. First, in order to satisfy the law of power conservation, mode-coupling coefficients are redefined and then, closed-form power-coupling coefficients are derived based on exponential, Gaussian, and triangular autocorrelation functions. Using the coupled-mode and coupled-power theories, impacts of random phase-offsets and correlation lengths on crosstalk in multi-core fibers are investigated for the first time. The simulation results are in good agreement with the measurement results. Furthermore, from the simulation results obtained by both theories, it is confirmed that the reciprocity is satisfied in multi-core fibers.

“…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].…”
