A polarization splitter based on a new type of dual-core photonic crystal fiber (DC-PCF) is proposed The effects of geometrical parameters of the DC-PCF on performances of the polarization splitter are investigated by finite element method (FEM) The numerical results demonstrate that the polarization splitter possesses ultra-short length of 1191 μm and high extinction ratio of 1187 dB at the wavelength of 155 μm Moreover, an extinction ratio greater than 20 dB is achieved over a broad bandwidth of 249 nm, ie, from 1417 nm to 1666 nm, covering the S, C and L communication bandsread more
