基于倏逝场特性的微纳光纤器件研究的中期报告
摘要：
本篇中期报告主要介绍了基于速度场特性的微纳光纤器件研究的进展和成果。首先介绍了研究对象——微纳光纤的制备方法和性质特征，分析了其在光学通信、生物医学检测和光子芯片等领域的应用前景。其次，详细描述了采用有限元方法对微纳光纤中光的传输及散射特性仿真模拟的过程和结果，分析了对不同材料及结构形式的微纳光纤的仿真模拟结果。最后，特别介绍了针对基于速度场特性的微纳光纤减振器的研究进展，包括其结构设计、制备工艺、测试方法和性能评估。实验结果表明，该减振器在宽带波长范围内均能有效地减小纤芯内相干光场与扰动光场之间的相互作用效应，为其在光学通信领域的应用提供了新思路和方法。
