摘要
采用SG-12SA作为镀膜设备, 研究了当金膜厚度相同的情况下, 光纤表面等离子体波传感器在有粘结层和无粘结层时的光谱特性; 当粘结层厚度相同时, 光纤表面等离子体波传感器对应不同金膜厚度的光谱特性。结果表明:对镀有同样金膜厚度的光纤表面等离子体波传感器, 纤芯与金膜之间有粘结层相对于无粘结层, 共振波长出现红移, 且共振深度减小; 对镀有同样粘结层厚度的光纤表面等离子体波传感器, 随着金膜厚度的增加, 共振波长亦逐渐发生红移。这些研究成果为以后研制性能优良的光纤传感器提供了参考, 同时为在直径为微米级的三维圆柱面上镀膜提供一定的指导意义。
Abstract
It not only compares the spectral characteristics of the optical fiber surface plasma resonance sensor between the boned and unbonded layer when they have the same thickness of the gold film, but also studies the optical fiber surface plasma resonance sensor at different thicknesses of the gold film when they have the same thickness of the adhesive layer. All of the studies are based on the coating equipment SG-12SA. The result indicates that the resonant wavelength of the optical fiber surface plasma wave resonance sensor red-shift and shallow gradually when the fiber core and the gold film having adhesive layer compares to non-adhesive layer, When the thickness of the adhesive layer is unchanged, the resonant wavelength is also red-shift with the thickness of the gold film increasing. These results not merely provide reference for making high-performance optical fiber sensor, but provide instructional information for coating on the micro-diameter of three dimensional cylinders.
