| contents | We propose a lensed-fiber based coupling strategy for low-loss interconnection between single-mode fibers and anti-resonant fibers. By optimizing structural and geometric parameters, the design simultaneously achieves high coupling efficiency and suppressed back-reflection. Experimental results demonstrate an insertion loss of 1.2 dB and back-reflection of -36.22 dB at 1550 nm, with excellent spectral stability (below 0.72 dB variation across 1500-1600 nm) and polarization insensitivity (below 0.4 dB polarization dependent loss). The compact structure not only facilitates the fabrication process, but also enables seamless ARF integration into existing optical networks, thereby addressing critical demands for high-capacity data transmission. |
