Abstract :
We present a novel dual-channel fiber-optic particle plasmon resonance (FO-PPR) sensor for refractive index sensing. The sensor, fabricated by a CO2 laser system, was realized by modification of gold sphere nanoparticles and gold nano-rods simultaneously in two different fiber sensing zones with a length of 2cm. This type of sensor has shown the capacity of simultaneously sensing two different channels of PPR signals with a relatively high refractive index sensitivity (~6.0/RIU).
