In this work, a photonic sensor based on photonic crystal fiber and surface plasmon resonance to analyze the refractive index (RI) of analytes varying from 1.440 to 1.480 is presented. A dual hexagonal lattice of air holes is reported in this proposed sensor design. The combination of titanium dioxide (TiO2) and gold (Au) is used as a plasmonic material in this sensor. The sensing capability of the proposed sensor is inspected in terms of wavelength sensitivity, amplitude sensitivity, sensor resolution, linearity of resonance wavelength, and figure of merit (FOM). Theoretical analysis of the sensor is performed for both quasi TM mode and quasi TE mode. Numerical investigation shows that wavelength sensitivity of 12 , 000 nm RIU − 1, is obtained for both TM mode and TE mode using the wavelength interrogation method. AS of 3307 and 3619 RIU − 1 is obtained for TM mode and TE mode, respectively, using the amplitude interrogation method. A maximum sensor resolution of 8.33 × 10 − 6 RIU is obtained for both TM mode and TE mode, respectively. The linear relationship of resonant wavelength with RI produces R2 = 0.9991 and R2 = 0.9970 for degree 2, for TM mode and TE mode, respectively. The FOM obtained from the proposed sensor is 139.53 and 187.50 for TM mode and TE mode, respectively.

双极化Au和TiO 2涂层光子晶体光纤表面等离子体激元共振折射率传感器的设计与分析:一种无关的传感方法
在这项工作中,提出了一种基于光子晶体光纤和表面等离子体共振的光子传感器,用于分析从1.440到1.480的分析物的折射率(RI)。在此拟议的传感器设计中报告了气孔的双六边形格子。二氧化钛(TiO2)和金(Au)的组合用作此传感器中的等离子材料。根据波长灵敏度,幅度灵敏度,传感器分辨率,共振波长的线性和品质因数(FOM),对所提出的传感器的传感能力进行了检查。对准TM模式和准TE模式都进行了传感器的理论分析。数值研究表明,使用波长询问方法,对于TM模式和TE模式均获得12,000 nm RIU-1的波长灵敏度。使用幅度询问方法分别为TM模式和TE模式获得3307和3619 RIU-1的AS。TM模式和TE模式分别获得8.33×10-6 RIU的最大传感器分辨率。对于TM模式和TE模式,对于2级,谐振波长与RI的线性关系分别产生R2 = 0.9991和R2 = 0.9970。从建议的传感器获得的FOM在TM模式和TE模式下分别为139.53和187.50。
