【摘要】：利用氢氟酸(HF)腐蚀石英光纤法制备出微纳米光纤,并研究了微纳米光纤的光学特性.实验中,利用CCD和数据采集卡,对腐蚀中的石英光纤进行实时监控.结果发现,微纳米光纤的光功率损耗随直径的减小,而呈指数增加.通过OptiFDTD软件模拟微纳米光纤的电场矢量分布,发现随着直径减小,微纳米光纤的倏逝场越来越强.当微纳米光纤的直径与输入光波的波长相近时,光波几乎只沿着光纤的表面传播.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,在传感器等领域具有很好的应用前景.
[Abstract]:Micro and nano fibers were prepared by hydrofluoric acid (HF) etching quartz fiber method, and the optical properties of micro and nano fibers were studied. In the experiment, CCD and data acquisition card are used to monitor the quartz fiber in real time. The results show that the optical power loss increases exponentially with the decrease of the diameter. The electric field vector distribution of micro / nano fiber is simulated by OptiFDTD software. It is found that the evanescent field of micro / nano fiber becomes stronger and stronger with the decrease of diameter. When the diameter of the fiber is close to the wavelength of the input light wave, the light wave propagates almost only along the surface of the fiber. The results show that the micro-nano fiber has the advantages of simple fabrication, small size, large evanescent field, and has a good application prospect in sensor and other fields.
