摘要
保偏光纤可以通过人为引入的高双折射,降低外界环境扰动引起的不可控双折射或偏振模色散给光纤传输带来的影响,在精密干涉传感、激光器系统、光通信等领域的应用中具有重要意义.相比传统实芯光纤受制于其纤芯高折射率材料的本征性缺陷,空芯光纤可以通过特定的微结构设计将光场限制在低折射率的空气纤芯中,具有低延迟、低色散、低非线性、高光致损伤阈值、抗干扰和可填充液体或气体的高灵活性等优势,因此保偏空芯光纤不仅能在上述应用领域发挥其性能的优势,还在高功率脉冲激光传输、生物化学分析等领域展现出广阔的应用前景.本文简要回顾了保偏空芯光纤的发展历程,对其中的设计思想和关键技术进行了讨论.
Abstract
Polarization maintaining fiber can reduce the influence of uncontrollable birefringence or polarization mode dispersion caused by environmental disturbance on transmission through artificially introduced high birefringence, and has applications in precision interference sensing, laser systems, optical communication, etc. Compared with traditional solid core fiber which is limited by the intrinsic defect of material, hollow core fiber can confine the optical field in low refractive index air core by specific microstructure design, with low delay, low dispersion, low nonlinearity, high photoinduced damage threshold, anti-interference and high flexibility of filling liquid or gas. Hollow core fiber which have polarization-maintaining feature can not only exert its performance advantages in the above applications, but also show broad prospects in high-power pulsed laser transmission and biochemical analysis application. In this paper, the development of polarization-maintaining hollow core fiber is briefly reviewed, and its design concepts and fabrication techniques are discussed.
