Abstract
The polarization characteristics of a dual-core photonic crystal fiber (PCF) with a metal wire filled into the cladding air hole between the two cores have been investigated. 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 −20 dB with bandwidths as great as 146 nm.
