摘 要: | 传统的THz单模单偏振光纤大部分都是基于实芯光纤设计的,增加了THz波的传输损耗。最近几年,也有一些关于空芯THz单模单偏振光纤的报道。但是,他们的带宽太窄,往往只能在单一频率附近工作,影响了单偏振器件在THz范围内的使用价值和技术优势。为了解决这些问题,设计了一种新颖结构的空芯THz单模单偏振器件。它拥有超过0.1 THz的带宽,工作频率范围从1.63 THz到1.73 THz。这种器件对于THz通信网络的建设和应用具有重要意义。

Abstract: | Traditional terahertz (THz) single-mode single-polarization (SMSP) fibers are mostly designed on the basis of solid fibers, which increases the THz wave transmission loss. In recent years, there have been a few reports about THz SMSP hollow core fibers; however, the fibers have narrow bandwidth, they can only work around a single frequency, which reduces the application value and technical advantages of single-polarization devices in THz networks. In order to solve these problems, a broadband THz SMSP fiber device was proposed. The fiber can achieve SMSP transmission from 1.63 THz to 1.73 THz with a bandwidth more than 0.1 THz. It has great significance for the establishment and application of THz communication network. |
