本文提出了一种以商用光纤为核心介质的新型太赫兹亚波长柔性光纤。所提出的双频光纤允许光信号在最里面的两层中传播，而太赫兹信号分布在光纤上，并且主要分布在无损泡沫包层中。在1550 nm和500μm处的传输损耗分别为0.2dB/km和0.034 dB/mm。该光纤结构紧凑，性价比高，在光学和太赫兹聚变传感、成像和非线性光电子学应用中具有广阔的应用前景。
This work proposes a new flexible terahertz subwavelength fiber using commercial optical fiber as the core medium. The proposed dual-band fiber allows the optical signals to propagate in the innermost two layers and the THz signal to distributed over the optical fiber and mostly in the lossless foam cladding. The propagation loss at 1550 nm and 500 μm are 0.2 dB/km and 0.034 dB/mm, respectively. The proposed fiber is compact and cost-effective, making it a promising candidate for optical and terahertz fusion sensing, imaging, and nonlinear optoelectronics applications.
