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 is used to optimize the diameter of the nano-gold column under the consideration of figure of merit, which relates to the sensitivity, resonance wavelength and resonance intensity. The optimized sensor has 70 nm gold nano-column coated on...
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,...
