微纳米光纤腐蚀动力学及其光学特性研究

Corrosion kinetics and optical properties of micro/nano fiber

  • 摘要: 本文利用氢氟酸腐蚀石英光纤的方法,制备出微纳米光纤,并通过实验及OptiFDTD软件研究微纳米光纤的光学特性。在实验中通过利用CCD与数据采集卡对氢氟酸腐蚀中的石英光纤进行实时监控来研究微纳米光纤的光功率损耗与直径的关系,发现微纳米光纤的光功率损耗与直径关系曲线大致符合玻尔兹曼函数模型。而通过OptiFDTD软件模拟微纳米光纤的波印廷矢量分布的结果,发现了随着微纳米光纤直径的减小,微纳米光纤的倏逝场会越来越大,而且当微纳米光纤直径与输入的光波波长相比拟时,光波几乎只沿着光纤的表面传播。实验结果表明微纳米光纤具有制备简单、尺寸小、倏逝场大等优良特性,在传感器等领域展示出诱人的应用前景。

     

    Abstract: This paper studied an experiment which can manufacture micro-nano optical fiber with the use of hydrofluoric acid, and using OptiFDTD to study its performance. In this experiment, with the use of CCD and data acquisition card for real time monitoring the process of HF etching and recording relationship between diameter of quartz fiber with the change in power loss, we found that the relationship between diameter of quartz fiber with the change in power loss roughly in line with the Boltzmann function model. Through simulating the Poynting vector distribution of micro-nano optical fiber with using OptiFDTD software, it shows that micro-nano optical fiber evanescent field will be bigger and bigger with?the decrease of the micro-nano optical fiber diameter, and when the micro-nano optical fiber diameter compare to the wavelength of incident light, waves almost along the surface of the fiber optic to propagate. As a result, with lots of favorable properties including simple preparation, small dimension,big evanescent field, micro-nano optical fiber shows attractive application prospect in the field of sensor and so on.
