Abstract :
We present an effective method for enhancing the refractive index sensitivity of a fiber-optic particle plasmon resonance sensor based on spatial light modulation technology. The sensor was realized by modification of spherical gold nanoparticles in the fiber sensing zone. Three different beam shapes were tested and one of the relatively high refractive index sensitivity (~12.67/RIU) was found. A 5% enhancement was found over sensors without beam modification.
