对太赫兹(THz)波段抑制耦合光纤(ICF)的传输损耗进行了多角度的数值分析。结果表明，堆芯边界支撑形状是影响约束损失的关键因素。模拟结果表明，支撑越接近圆弧，约束损耗越小。此外，支柱厚度和材料折射率决定了低损耗区的频率和带宽。随着压杆厚度和材料折射率的减小，低损耗区向高频方向移动，低损耗区的宽度变宽。此外，当模拟中考虑材料吸收时，ICF平均传播损耗仍比材料吸收损耗低三个数量级左右。所得结论对太赫兹ICF的设计和制作具有一定的指导意义。
A multi-perspective numerical analysis of propagation loss in inhibited coupling fibers (ICFs) in terahertz (THz) band is presented. It is shown that the core boundary strut shape is a critical factor affecting the confinement loss. The simulation results demonstrate that the closer to a circular arc the struts, the lower the confinement loss. Furthermore, the strut thickness and the material refractive index determine the frequencies and the bandwidths of the low loss region. With the decrease of the strut thickness and material refractive index, the low loss region will be shifted toward the higher frequency, and the widths of low loss regions will be broadened. Besides, when material absorption is considered in simulation, the ICFs averaged propagation loss is still about three orders of magnitude lower than the material absorption loss itself. The conclusions could give valuable guidance for the design and fabrication of THz ICFs.
