“…[19] In 2022, Zhang investigated a compact gallium sulfide DC-PCF PBS, whose working bandwidth is 170 nm and splitting length is 277.1 µm. [20] Generally speaking, the performances of the DC-PCF PBS can be improved by selectively filling different functional materials (such as gold, silver, and liquid crystal) into the cladding air holes. [21] In 2021, Zhang et al designed a gold wire-filled DC-PCF PBS with the three kinds of air holes, where the working bandwidth is 120 nm and the splitting length is 249.12 µm.…”

In this paper, a novel polarization beam splitter (PBS) based on dual-core photonic crystal fiber (DC-PCF) is proposed. The proposed DC-PCF PBS contains two kinds of lattices and three kinds of air holes to form the asymmetrical elliptic dual-core structure. By using the full-vector finite element method, the propagation characteristics of the proposed DC-PCF PBS are investigated. The simulation results show that the bandwidth of the proposed DC-PCF PBS can be up to 340 nm, which covers the S + C + L + U communication bands, the shortest splitting length is 1.97 mm, and the maximum extinction ratio appears near wavelength 1550 nm. Moreover, the insertion loss of the proposed DC-PCF PBS is very low. It is believed that the proposed DC-PCF PBS has important applications in the field of all-optical communication and network.
