【 摘 要 】

This study demonstrates the polarization-maintaining (PM) solid-core anti-resonant fiber (SC-ARF) in mid-infrared region (MIR) for the first time. Numerical simulation results indicated that the fundamental mode (FM) birefringence could be induced by filling the designed structural model with different materials. With the optimized cladding tubes thickness of 0.82 μm, fiber presented the birefringence coefficient (Δn) about 1.56 × 10−5 and the confined loss (CL) less than 0.1 dB/m, which are of great importance in polarization-sensitive systems. Moreover, by increasing the tubes number and adjusting the incident laser wavelength, the reduced CL values and band-pass performances were observed, which could significantly promote the fabrication of PM filters in MIR.
