摘　　要：太赫兹(Terahertz, THz)技术作为一项非常重要的交叉前沿学科,给环境检测、生物医学、空间通信等领域带来了深远的影响,但因为THz波导传输性能的影响,THz技术综合发展仍然受到一定限制。光子晶体光纤(Photonic Crystal Fiber, PCF)作为一种新型THz波导,拥有无限单模特性、色散灵活可调、可控的非线性、高双折射等特性,极大的促进了THz技术的发展。首先根据PCF的结构特点总结了实芯PCF(Solid Core PCF, SC-PCF)和空芯PCF(Hollow Core PCF, HC-PCF)各自的发展历程、导光机理和光学特性;其次,梳理了用于THz波导的PCF存在的问题以及对应的解决方法;然后,着重介绍了PCF在THz时域光谱、THz传输与通信以及THz光纤耦合传感中的应用;最后,对PCF在THz技术的应用做了总结与展望。Terahertz(THz)technology,as a very important interdisciplinary field,has brought profound impacts to fields such as environmental detection,biomedicine,and space communication.However,due to the impact of THz waveguide transmission performance,the comprehensive development of THz technology is still limited.Photonic Crystal Fiber(PCF),as a new type of THz waveguide,has infinite single mode characteristics,flexible and adjustable dispersion,controllable nonlinearity,high birefringence,and other characteristics,greatly promoting the development of THz technology.This article first summarizes the development history,light guiding mechanism,and optical characteristics of Solid Core PCF and Hollow Core PCF based on the structural characteristics of PCF;Secondly,the problems and corresponding solutions of PCF used for THz waveguides were summarized;Then,the application of PCF in THz time-domain spectroscopy,THz transmission and communication,and THz fiber coupled sensing was emphasized;Finally,a summary and outlook were made on the application of PCF in THz technology.
