Numerical investigation shows that the inclusion of the metal wire greatly changes the coupling characteristics of the modes in the two cores. In fact, the coupling lengths of the two polarizations show increased difference, which leads to the possibility of designing a dual-core PCF with a coupling length ratio of 1:2 for the two polarization states. The proposed polarization splitter shows extinction ratios as low as −20dB with bandwidths as great as 146nm.
