Ultra-sensitive surface plasmon resonance fiber optic sensors based on gold nanoparticles

Abstract

Plasmonic properties of metals such as gold is the main factor in the development of optical fiber sensors. Plasmonic property is created by exciting the surface plasmon polaritons by laser radiation. These properties are usually used in boosting and detection. The article examines and compares the collected information such as the length of the fiber optical sensor and the sensitivity of sensors including wave guides, fiber brag gratings and Wagon Wheel optical fiber in recent years.
