摘　　要：金属纳米晶复合光纤结合了金属纳米晶独特的局域表面等离子体共振(LSPR)和光纤器件尺寸小、结构简单、性能稳定、抗干扰能力强等优点。其中,金属纳米晶LSPR引起的高非线性效应、金属增强发光、表面增强拉曼散射等效应能够赋予光纤新功能、高性能,而光纤表面倏逝波传输的特性可以极大地提升金属纳米晶的LSPR激发效率。因此,金属纳米晶复合光纤在非线性光学调制、光纤激光器、物理和生化传感与检测方面都有重要的应用,受到了研究者的广泛关注。从金属纳米晶LSPR机理、制造方法、应用等方面对金属纳米晶复合光纤进行介绍,并就其未来发展作展望。Metal nanocrystals hybridized optical fibers (MNCs-OFs) combine the unique localized surface plasmon resonance (LSPR) property afforded by metal nanocrystals and the advantages of small size, simple structure, stable performance, and high resilience to disturbance of optical fibers. On the one hand, high optical nonlinearity, metal enhanced fluorescence, and surface enhanced Raman scattering, which are caused by LSPR of metal nanocrystals, can impart optical fiber with new functionalities and better performance. On the other hand, evanescent wave transmitting property of optical fiber can tremendously enhance the excitation efficiency of LSPR of metal nanocrystals. Therefore, MNCs-OFs are very useful in many applications such as optical tuning, fiber laser, physical/biochemical sensing and detection, which have drawn extensive research interests. Here, we make a brief review to the LSPR mechanism of metal nanocrystals and the fabrication and applications of MNCs-OFs, and provide a prospect to the future development of this type of optical fibers.
