Abstract: (1117 Views)
In recent years, the need to analyze various physical, chemical, and biological parameters with the help of optical fiber sensors has increased. The use of fiber-optic surface plasmon resonance is a suitable alternative to prism-based structures. In this paper, the H-shaped optical fiber sensor is analyzed to investigate changes in the fiber confinement loss spectrum in exchange for changes in the refractive index of the assay material, the effect of changing the thickness of gold, insulation, and depth of the polished area. The wavelength sensitivity, amplitude sensitivity, and figure of merit (FOM) of this structure are 6833.33 (nm / RIU), 2539 (1 / RIU), and 52.197, respectively. A model like this can be effective in measuring biological parameters.
