A refractive index optical fiber sensor based on surface plasmon resonance technology is demonstrated. The sensing device is a multimode optical fiber in which half of the core is polished away and a thin‐film layer of gold is deposited. We measure the spectrum‐difference variations and the resonance wavelength shifts for different refractive index solutions. In terms of the experimental data, the characteristics including resolution, sensitivity, and signal‐to‐noise ratio for the sensor are obtained. © 2012 Wiley Periodicals, Inc.
