In this paper, we investigate the Surface Plasmon Resonance (SPR) provided by Au coated optical fiber sensor utilized as a refractometer. It is observed that SPR are formed at the dielectric metal boundary interface in the sensing region. In this work, two different thicknesses of Au thin later deposited on polymer optical fiber were experimentally studied in exposure to the solutions with various refractive index. The obtained results revealed that the SPR wavelength appeared in the transmitted spectra shifts to the longer wavelength according to the changes in the refractive index of surrounded solution. Moreover, it could be observed that the fiber coated with thicker Au layer with 53 and 98 nm thickness shows a more efficient sensing performance rather than that of the thin one but Sensitivity was obtained for a sensor with a thickness of 807 nm / RIU and for another sensor with 396 nm / RIU. The linearity and high sensitivity obtained by the proposed sensing fibers point to a versatile sensing probe for the development of SPR-based biosensors.
