Abstract
We propose and investigate a Dshaped photonic fiber refractive index sensor with rectangular lattice based on surface plasmon resonance In such sensor the nanoscale gold metal film is deposited on the flat surface where it is side polished Numerical results show that the average sensitivity of Aumetalized surface plasmon resonance SPR sensor could reach as high as 8129 nm/refractive index unit RIU in the dynamic index range from 135 to 141 as well as 2000 nm/RIU from 133 to 135 Compared to conventional Aumetalized SPR sensors the performance of our device is obviously better and the production process is greatly simplified
