We numerically investigate the polarization-dependent coupling in dual-core photonic crystal fibers (PCFs) selectively filled with gold wires in air holes. It is shown that the even and odd supermodes exhibit significantly different dispersion and loss when one gold wire is filled in between two cores. The enhanced birefringence and polarization-dependent attenuation of the supermodes support the separation of two orthogonally polarized components as well as polarization-dependent transmissions with a high degree of polarization in gold-filled dual core PCFs. Our study suggests that a gold-filled PCF coupler is a new possibility for applications on polarization beam splitters and polarizers.
