A new type of hybrid structure hollow-core polarization-maintaining fiber with high polarization-maintaining, low loss and excellent bending characteristics in the near-infrared band is proposed. The innovative hybrid structure is formed by adding a double-layer anti-resonance arc-shaped thin-wall in the core of the 19 cell photonic bandgap (PB) hollow-core fiber. On the premise of maintaining the excellent bending characteristics of the PB hollow-core fiber, the birefringence is enhanced by reducing the symmetry of the anti-resonance (AR) effect. The results of numerical simulation show that the maximum birefringence is 1.36×10-3 at the wavelength of 1 550 nm, and the corresponding confinement losses of the two fundamental modes are 1.24×10-5 dB/km and 4.64×10-4 dB/km, respectively. When the fiber is bent to a bending radius of 5 mm, the confinement loss of the two polarization fundamental modes can be less than 10-2 dB/km. The analysis of fabrication robustness shows that the PB-AR hybrid structure fiber has good transmission and polarization-maintaining characteristics even when the curvature of the arc-shaped thin-wall is changed in a small range. The PB-AR hybrid structure will provide a new impetus for structural innovation and exploration of hollow-core fiber with high polarization-maintaining and low loss characteristics under small bending radius. The excellent performance of the hybrid structure fiber will also promote the application of the hollow-core polarization-maintaining fiber.
