Paper Abstract

In this paper, a highly sensitive surface plasmon photonic crystal fiber (PCF) biosensor is reported and studied to monitor glucose concentration. The suggested design is based on a well-known large mode area (LMA) single mode PCF infiltrated by a plasmonic material. Additionally, an etching process is applied to increase the biosensor sensitivity. The numerical analysis is obtained using a full vectorial finite element method (FVFEM). The suggested biosensor based on a commercial PCF with plasmonic rod achieves sensitivity as high as 7900 nm/RIU with corresponding resolution of 1.26 × 10-5RIU-1. The analysis also reveals that the proposed biosensor has a linear performance which is needed practically. Therefore, the reported biosensor has advantages in terms of fabrication feasibility and high linear sensitivity
