Abstract

This paper investigates the optical characteristics of a single mode fiber (SMF) based surface plasmon resonance (SPR) sensor. Utilizing the finite element method (FEM) in COMSOL, a numerical model of the SMF-based sensor is developed and its performance evaluated based on varying gold thicknesses (30 nm, 40 nm, and 50 nm). Results show that thinner coatings lead to deeper evanescent wave penetration and higher field intensity at the sensing interface for air contaminant monitoring applications.
