中文摘要： 微纳光纤在光通信和传感领域具有广泛应用前景。随着光通信和传感技术的进一步发展，要求实现低损耗、快响应、高灵敏度等高性能和复合功能的微纳光纤。基于贵金属纳米结构的LSPR（局域表面等离子体共振）效应可在纳米尺度上实现电磁场局域增强，在构建高性能微纳光纤方面展现了独特的优越性。本项目拟研究贵金属纳米粒子掺杂微纳光纤的可控制备，通过贵金属纳米粒子的LSPR效应调控微纳光纤的光学特性，构建高性能复合功能微纳光纤。我们将通过贵金属纳米粒子尺寸、形状、排列的操控以及表面修饰来调控微纳光纤的光学特性，研究贵金属纳米粒子在微纳光纤中形成和排列的动力学原理。作为对实际应用的基础性探索，本项目还将研究光信号在单根贵金属纳米粒子掺杂微纳光纤中的传输和损耗，结合实验和理论模拟研究单根光纤的近场场强增强因子分布和消光光谱，演示基于单根微纳光纤LSPR的SERS(表面增强拉曼散射)效应，构建超高灵敏光纤传感器件。

英文摘要： M/NOF (Micro/nano optical fibre) promises great prospect for wide range of applications in constructing integrated optical circuits and optical sensing. High-performance and multifunctional M/NOF with low loss, fast response and high sensitivity are required to meet the further development of optical communication and sensing technologies. LSPR (Localized surface plasmonic resonance) based on noble metal nano-structures are capable of realizing local enhancing of electromagnetic field, thus has been demonstrated unique versatility in constructing high-performance M/NOF. This project will explore technologies for controllable fabrication of noble metal nanoparticles doped M/NOF, aiming at tailoring optical properties of M/NOF via LSPR of noble metal nanoparticles, thus constructing high-performance and multifunctional M/NOF. Tailoring of the optical properties of M/NOF will be realized through adjusting size, shape, arrangement of noble metal nanoparticles, and their surface modification, when the dynamics for formation and arranging of metal nanoparticles in M/NOF will also be investigated. For fundamental exploration before practicle applications, this project will also investigate the transmission and loss of light in single noble metal nanoparticles doped M/NOF, study distribution of near field enhancing fact
