摘　　要：光纤传感器具有体积小、重量轻、抗电磁干扰等优点,被广泛应用到电力系统、生物医疗、化学化工等领域。传统加工制作光纤传感器的方法需要昂贵的仪器设备,而且工艺复杂。提出1种在光纤端面加工的周期纳米金属阵列结构。通过将光纤端面磨削成不同角度的倾斜角,进行表面等离子体共振效果实验。实验结果表明,当倾斜角度为7°时纳米阵列光纤传感器的共振激发表现得最强,传感器达到最佳传感状态。Optical fiber sensor has the advantages of small size,light weight,anti electromagnetic interference,which is widely used in power system,biomedical,chemical and other fields.The traditional method of manufacturing optical fiber sensor needs expensive equipment and complicated technology.In this paper,a periodic nano metal array structure fabricated on the fiber end face is proposed.The surface plasmon resonance(SPR)experiment is carried out by grinding the fiber end surface into different inclined angles.The experimental results show that when the tilt angle is 7°,the resonance excitation of the nano array optical fiber sensor is the strongest,and the sensor reaches the best sensing state.
