We propose and numerically analyze a broadband single-mode low-loss high-birefringence hybrid hollow-core polarization-maintaining fiber (HC-PMF) with high fabrication feasibility. This hybrid HC-PMF incorporates two pairs of anti-resonant arc-layers, made of two materials with a slight refractive index difference, into the core of a 19-cell hollow-core photonic bandgap fiber. High birefringence is induced by breaking the symmetry via material property differences, rather than through traditional geometric asymmetries in shape or wall thickness. Numerical results demonstrate that high birefringence, low loss and excellent single-mode performance can be simultaneously achieved across a wide wavelength range from 1.47 μm to 1.6 μm. At the wavelength of 1.55 μm, birefringence can reach 1.11 × 10-4, and the loss of x-polarized and y-polarized mode are 9.64 dB/km and 8.78 dB/km, respectively. Especially, higher-order mode extinction ratio reaches up to 1.44 × 1010 and thus excellent single-mode performance can be achieved. Moreover, the fiber maintains stable performance under a tight bending radius of 8 mm and exhibits excellent fabrication tolerance. This study simplifies the design of asymmetry for high-birefringence hollow-core fibers through a material engineering strategy, significantly enhancing fabrication feasibility and making it promising for polarization-sensitive systems such as fiber-optic gyroscopes and high-power polarization-maintaining fiber lasers.
