Surface plasmon photonic crystal fiber biosensor for glucose monitoring

In this paper, design consideration of a surface plasmon photonic crystal fiber (PCF) biosensor for Glucose monitoring is presented and analyzed. Based on a well-known large mode area (LMA) PCF, two different configurations have been studied to investigate the effect of the etching process. The numerical results show that the plasmonic D-shaped PCF after etching three rows of air holes can achieve sensitivity of 200 nm/RIU with corresponding resolution of 1.3 ×10

. The analysis is carried out using full vectorial finite element method (FVFEM) with perfect matched layer (PML) boundary conditions.
