In this paper, a theoretical analysis for surface plasmon resonance sensor with the buffer layer of magnesium fluoride has been carried out. The numerical treatment is based on side polished single mode fiber SPR sensor and Drude model of metals. Meanwhile, the comparison for conventional SPR sensor, symmetrical SPR sensor and long range SPR sensor has been performed. On the basis of all these studies,...
In this paper, a theoretical analysis of figure of merit (FOM) of a surface plasmon resonance (SPR) sensor with a one dimensional (1D) Photonic Crystal (PC)and an anti-oxidizing layer of the graphene has been carried out. The numerical simulation is based on side polished multi mode fiber SPR sensor with the 75 μm residual fiber thickness and 20nm silver film thickness. Meanwhile, the comparisons...
In this paper, a surface plasmon resonance fiber sensor based on gold nano-column array instead of gold film is designed and optimized. The finite element method (FEM) is used to optimize the sensitivity, resonance wavelength and resonance intensity of the fiber sensor relate to the diameter of the nano-gold colunm. The optimized sensor has 70 nm gold nano-column coated on a D-shaped single mode fiber...
