High-performance tapered fiber surface plasmon resonance sensor based on graphene/Ag/TiO2 layer
[post]
2021
unpublished
In this paper, a highly sensitive surface plasmon resonance sensor is proposed on the basis of a miniature tapered single-mode fiber. The sensing area of the tapered fiber is coated with graphene, silver and titanium dioxide layer. The graphene layer is used to increase the light absorption rate, and the titanium dioxide layer is used to protect the silver layer from oxidation and improve the sensor sensitivity due to its high dielectric constant. And optimizing the thickness of graphene,
