Abstract

In this paper, a dual hollow-core anti-resonant fiber polarization beam splitter (DHC-ARF PBS) with ultra-wide splitting bandwidth is proposed. The effects of the structure parameters of the DHC-ARF PBS on the splitting performances, including the coupling length, coupling length ratio, confinement loss, and higher-order mode extinction ratio (HOMER), are investigated using the finite element method. The simulation results show that under the optimal structure parameters, the proposed DHC-ARF PBS has larger HOMER (> 100) within the working wavelength range, indicating its good single-mode transmission characteristics. Moreover, the proposed DHC-ARF PBS has a short splitting length of 2.07 cm and an ultra-wide splitting bandwidth of 610 nm (1320 ~ 1930 nm), which covers the whole E, S, C, L, and U bands and a portion of O band. It is believed that the proposed DHC-ARF PBS will have significant applications in the optical communication and sensing systems.

O + E + S + C + L + U波段双空心抗谐振光纤偏振分束器设计

提出了一种具有超宽分裂带宽的双空心抗谐振光纤偏振分束器（DHC-ARF PBS）。采用有限元方法研究了DHC-ARF PBS结构参数对劈裂性能的影响，包括耦合长度、耦合长度比、约束损耗和高阶模消光比（HOMER）。仿真结果表明，在最优结构参数下，所提出的DHC-ARF PBS在工作波长范围内具有较大的HOMER (> 100)，表明其具有良好的单模传输特性。此外，所提出的DHC-ARF PBS具有2.07 cm的短分裂长度和610 nm （1320 ~ 1930 nm）的超宽分裂带宽，覆盖了整个E、S、C、L和U波段以及部分O波段。认为所提出的DHC-ARF PBS在光通信和传感系统中具有重要的应用价值。
