设计了一种基于Kagome光子晶体结构的低损耗空芯太赫兹波导，并利用3D打印技术制作了该波导。已经通过使用THz时域光谱对3D打印波导进行了表征。结果表明，在0.2-1.0 THz范围内，波导的平均功率传输损耗为0.02 cm（-1），在0.75 THz时损耗最小，约为0.002 cm（-1）。更有趣的是，它可以简单地机械拼接，而无需任何额外的对齐，同时保持出色的性能。3D打印技术将是一种具有良好可控特性和低成本的Kagome THz波导的有前途的解决方案。(C)2016美国光学学会
A low-loss hollow core terahertz waveguide based on Kagome photonic crystal structure has been designed and fabricated by 3D printing. The 3D printed waveguide has been characterized by using THz time-domain spectroscopy. The results demonstrate that the obtained waveguide features average power propagation loss of 0.02 cm (1) for 0.2-1.0 THz (the minimum is about 0.002 cm(-1) at 0.75 THz). More interesting, it could be simply mechanically spliced without any additional alignment, while maintaining the excellent performance. The 3D printing technique will be a promising solution to fabricate Kagome THz waveguide with well controllable characteristics and low cost. (C) 2016 Optical Society of America
