Abstract A novel ultra-broadband polarization splitter based on dual-core photonic crystal fiber (DC-PCF) is designed. The full-vector finite element method (FEM) and coupled-mode theory are employed to investigate the characteristics of the polarization splitter. According to the numerical results, graphene-filled layer can not only broaden the working bandwidth but also reduce the size of polarization splitter. Furthermore, the fluorine-doped region and the germanium-doped region could broaden the bandwidth. Apart from that, the 4.78-mm-long polarization splitter can achieve an extinction ratio of -98.6 dB at the wavelength of 1550 nm. When extinction ratio is less than -20 dB, the range of the wavelength is 1027-1723 nm with a bandwidth of 696 nm. Overall, the polarization splitter can be applied to all-optical network communication system in the infrared and near-infrared wavelength range.

We propose a new polarization splitter (PS) based on Ti and liquid infiltrated photonic crystal fiber (PCF) with high birefringence. Impacts of parameters such as shape and size of the air holes in the cladding and filling material are investigated by using a vector beam propagation method. The results indicate that the PS offers an ultra-short length of 83.9 μm, a high extinction ratio of −44.05 dB, and a coupling loss of 0.0068 dB and at 1.55 μm. Moreover, an extinction ratio higher than −10 dB is achieved a bandwidth of 32.1 nm.
