A High Sensitivity Surface Plasmon Resonance Biosensor Based on Photonic Crystal Fibers for Refractive Index Sensing
A photonic crystal fiber (PCF) based surface plasmon resonance (SPR) refractive index (RI) sensor is proposed and demonstrated. The gold as a plasmonic material is coated outside of the PCF to realize RI sensing and the influence of various geometrical parameters on the sensing characteristics are investigated by using finite element method (FEM). Results show that the proposed sensor realizes a maximum wavelength sensitivity (WS) of 10300nm/RIU with a wavelength resolution of 7.767 × 10−6. Moreover, the maximum amplitude sensitivity (AS) of 3465 RIU−1 is realized in the detection range from 1.33 to 1.41. This biosensor exhibits high sensitivity, simple structure and convenient detection, which is very suitable for the bio-sensing or diagnosis of cancers.
