Abstract
A surface plasmon resonance based fiber optic sensor is presented experimentally using silver and nickel oxide layers. The sensitivity analysis of the sensor has been carried out. Also, the influence of the nickel oxide layer thickness upon the sensitivity has been examined. The sensitivity is enhanced with the increase in thickness of nickel oxide layer up to 10 nm and decreased at larger values. The sensor composed of 40 nm silver-10 nm nickel oxide layers provides the highest sensitivity.
