In this paper, a simple structure dual-core photonic crystal fiber (SS-DC-PCF) polarization beam splitter (PBS) based on the surface plasmon resonance (SPR) effect and symmetric dual-core coupling mode theory is proposed. For the proposed SS-DC-PCF-1 PBS, the coupling lengths (CLs) and coupling length ratio (CLR) are analyzed, and the variations of the normalized output powers with the propagation length are investigated for the chosen wavelengths 1.434, 1.451, and 1.469 µm. The extinction ratio in cores A and B are compared at the three splitting lengths (SLs) 170, 173, and 176 µm. When the optimal SL is 176 µm, the splitting bandwidth (SB) is 255 nm (1.437–1.692 µm), and the insertion loss (IL) is less than 0.043 dB. The regulations of the CLs and CLR with the change of the structure parameters are analyzed. For the proposed SS-DC-PCF-2 PBS, the optimal SL is 232 µm, the SB is 201 nm (1.249–1.450 µm), and the IL is less than 0.042 dB. Finally, it is demonstrated that the total SB of the proposed SS-DC-PCF-1 PBS and SS-DC-PCF-2 PBS is 443 nm (1.249–1.692 µm), which can cover the O + E + S + C + L + U band, even if the gold film thickness changes by ± 1 n m . The proposed SS-DC-PCF PBS has excellent performances, such as ultrashort SL, ultrawide SB, ultralow IL, and good error-tolerance rate. It will have important applications in all-fiber optical systems.

In this paper, a novel silicon dual-core photonic crystal fiber (Si-DC-PCF) polarization beam splitter (PBS) based on surface plasmon resonance effect is proposed. The mode coupling characteristics between the X and Y-polarized even and odd modes and surface plasmon polariton mode are analyzed by using the finite element method and coupled-mode theory. The influences of the structure parameters of the Si-DC-PCF on the coupling length and coupling length ratio are investigated. The normalized output power of the X and Y-polarized modes in the cores A and B and the corresponding extinction ratio are also discussed. By optimizing the structure parameters of the Si-DC-PCF, the PBS length of 192 μm and bandwidth of 830 and 730 nm in the cores A and B are achieved. It is believed that the proposed Si-DC-PCF PBS can find important applications in the mid-infrared laser and sensing systems.

“…In parallel, optical fiber sensors have attracted widespread attention due to their advantages of compact size, high stability, repeatability, and electromagnetic immunity in remote sensing ( Zheng et al., 2018 ; Ding et al., 2019 ; Li et al., 2018a , 2018b , 2019a , 2019b ; Cai et al., 2020 ; Loyez et al., 2022 ; Yesudasu et al., 2021 ; Polley et al., 2019 ). Combined with biochemical sensing, fiber can provide cheap and remote online measurement of chemicals or biochemicals.…”
