“…The polarization effects have a substantial impact on a variety of polarization-sensitive optical ber systems, such as ber-based gyroscopes [1], ber sensors [2,3], polarization lters [4], polarization splitters [5,6], and so on [7,8]. Since polarization and birefringence are closely connected, high birefringence (Hi-Bi) has been attained immense interest during the past several years by researching and creating solid-core bers with polarization maintaining (PM) features by adding anisotropy [9] (such as ellipticity) or stress [10] to the ber's core.…”

In this paper, a single ring hollow-core anti-resonant fiber (HC-ARF) with five elliptical nested tubes and a silicon layer is presented and investigated. The geometrically optimized HC-ARF, proposed here, exhibits highest birefringence of 2.95×10− 4 at 1550 nm by maintaining a birefringence level of > 10− 4 for a bandwidth of 58 nm. The confinement loss of this fiber reaches to a very low value of 7.57×10− 3 dB/m at 1550 nm and sustains a loss of < 0.75 dB/m within the highly birefringent region. A higher order mode extinction ratio of 51, for our fiber, ensures a singlemode operation at 1550 nm.Moreover, the HC-ARF offers low bend loss of 0.08 dB/m at 2 cm of bend radius and the bend loss remains < 0.08 dB/m from 3 cm of bend radius to onwards.

“…This fiber introduces two silicon tubes containing nested tubes to create an air gap and exhibits good single-mode characteristics. In 2022, Shaha et al introduced a DHC-ARF with a length of 2.152 cm, but it lacked good single-mode characteristics within its 340 nm wide operating bandwidth [17]. In the same year, Ni et al proposed a DHC-ARF with a length of 6.45 cm and an operating bandwidth of 400 nm [18].…”

Apolarization beam splitter based on a dual hollow-core anti-resonant fiber is proposed. In the horizontal direction, elliptical shapes are introduced to form two hollow cores, with an air gap between the ellipses serving as a mode-coupling channel. Using the finite element method, a specific analysis is conducted on the influence of various structural parameters of the dual hollow-core anti-resonant fiber on the coupling length of the x-polarized and y-polarized modes, as well as the extinction ratio of higher-order modes.Optimizing the structural parameters of the fiber has led to the design of a dual hollow-core anti-resonant fiber polarization beam splitter that is exceptionally compact, measuring just 1.306 cm in length. This device achieves a broad bandwidth of 420 nm ranging from 1.53 µm to 1.95 µm and maintains superior single-mode characteristics within this wavelength spectrum. The novel dual hollow-core anti-resonant fiber is poised to play a significant role in the optical communication systems and optical network technologies.

“…In 2021, Jia et al designed a single-mode PBS based on the DHC-NCF with two elliptical tubes nested with the circular tubes, where the PBS length was 8.15 cm and the bandwidth was 370 nm (1.28 to 1.65 μm) [31]. In 2022, Shaha et al demonstrated a short-length DHC-NCF with two elliptical tubes splitting the two cores, where the bandwidth covered the wavelength range from 1.285 to 1.625 μm [32]. In the previous works, the reported DHC-NCF PBSs cannot cover the shorter wavelength range, such as the O and E bands.…”

In this paper, a dual hollow-core negative curvature fiber is proposed for the polarization beam splitter. The effects of the structure parameters of the dual hollow-core negative curvature fiber on the coupling length and coupling length ratio of the x -polarized and y -polarized core modes and the higher-order mode extinction ratio are analyzed by the finite element method. Moreover, the normalized output powers of the x -polarized and y -polarized modes in the cores A and B and the corresponding extinction ratio are also investigated by the mode coupling theory. The simulation results show that a dual hollow-core negative curvature fiber polarization beam splitter with the length of 6.45 cm can achieve a broad bandwidth of 400 nm (1.23–1.63 µm), covering the O + E + S + C + L communication band. In addition, the higher-order mode extinction ratio is greater than 100 in the considered wavelength range, which means that it has good single-mode characteristics. It is believed that the proposed dual hollow-core negative curvature fiber polarization beam splitter will have significant applications in the optical communication system.
