Optical fiber-based sensor using the localized surface plasmon resonance effect
Date
2024
Abstract
This paper reports and experimentally demonstrates a localized surface plasmonic resonance (LSPR) refractive index sensor based on gold nanoparticles (AuNPs) coated multimode optical fiber. The optical properties of the AuNPs were modelled using the finite element method (FEM) simulation model. AuNPs were synthesised chemically and immobilized on the surface of a multimode fibre (MMF) to realise the LSPR fiber optic sensor. Our results show that the proposed LSPR sensor demonstrates a refractive index (RI) sensitivity of 3.7 AU/RIU in the intensity domain.
