  • Abstract
    This study introduces an efficient D-shaped sensor for refractive index (RI) sensing based on the surface plasmon resonance (SPR) phenomenon. The sensor design was examined through numerical simulations utilizing the finite element method (FEM). The calculations revealed that the proposed fiber demonstrates particular suitability for sensing within the wavelength spectrum spanning from 0.5 to 0.7μm. Our results yielded a remarkable wavelength sensitivity and substantial RI resolution of 9500 nm/RIU and 6.5 ×10^–6 RIU, respectively which observed as the analyte RI ranged 1.33~1.36. Additionally, a maximum amplitude sensitivity of 215 RIU–1, accompanied by an impressive linearity of 0.99862 was acheived.
