Nonorthogonal coupled mode theory is used to analyze the impact of iron nano- inclusion in the TE mode coupling between two integrated optical waveguides structures. In the first case, the nano-inclusion fractions are included in an identical manner in both waveguides, and in the second the nano-inclusion are added only in one of the waveguides. The structures beating lengths strongly depends on the inclusion filling factor and the thickness of the cladding layer. They reduce with increasing inclusion-filling factors, reaching a 70% and a 56% reduction with respect to the lossless case, for the identical and non-identical cases, respectively. Cladding thickness increases the beating length reducing the structure total power as filling factor increases, for the identical case, and depicting a inflection point for the non-identical case where the total power increases.
