Abstract

During   this work, fiber optic sensor based on surface Plasmon resonance (SPR) was prepared. The sensor of SPR was configured by coating a thin layer of gold film on the end of a cleaved optical fiber by a sputtering technique.  The source of white light   was utilized to produce a series   of wavelengths and excites surface Plasmon resonance at the fiber tip. SPR sensor was immersed into media with different refractive indexes in the range )1-1.58( including their similar Plasmon resonance wavelength shifts were saved by optical spectrum analyzer and noticed reflected light on a personal computer. Experimental results that obtained show there is a redshift when increasing the refractive index of solutions and sensitivity reach 298nm/ RIU, and resolution 4.31x .
