摘要: We report the polarization-maintaining properties of a highly elliptical core fiber surrounded by trench that was designed to optimize modal effective indices and bending loss for total five spatial modes (10 channels). In addition asymmetric structure, birefringence is increased thermal stress introduced during fabrication. The results show larger than 10−4 all guided modes. mode stability evaluated selectively exciting/detecting each while perturbing fiber. This few-mode interest multiple-input multiple-output (MIMO)-free division multiplexing transmission systems.
