摘要
基于光学异常透射现象的光纤传感器,因其具有高度的近场增强效应和介电环境的高度敏感性等优点,在化学、生物医学等领域有广泛的应用前景。但是由于在光纤端面加工周期纳米结构需要复杂的工艺或者昂贵的微加工仪器,限制了基于光学异常透射现象的光纤传感器的发展。针对这一问题,提出了模板转移法在光纤端面加工金属周期纳米结构,并搭建实验系统对应用该方法制作的光纤传感器的传感特性及其物理机理进行了研究。实验结果表明,模板转移法能够很好地完成在光纤端面加工高质量的周期金属纳米结构。应用该方法制作的光纤传感器具有很好的传感特性,传感器的最高灵敏度达到594.45nm·RIU^(-1),品质因数值达到33.12。
Optical sensors with extraordinary optical transmission phenomenon have proved t o hold great potential in the field of chemical and biomedical due to its signif icant near-field enhancement and high sensitivity to the dielectric environment.However,the utility of this kind of optical fiber sensors is largely limite d by its complex nanofabrication methods and expensive instruments.Here to rel ieve these restrictions,a method of transferring templates was used to process periodic metal nanostructures onto endface of optical fibers.And an experimen tal setup was built to study sensing characteristics and sensing mechanism of th e optical fiber sensors.The obtained results indicated high quality periodic m etal nanostructures can be transferred onto endface of optical fibers by the tem plate transfer method.The sensitivity of the resulting sensor to refractive in dex change was 594.45 nm·RIU-1(refractive index unit)and figure of meri t(FOM)achieved 33.12.
