Generation of surface plasmon on graphene coated optical fiber for sensor applications

This article is devoted to the generation of surface plasmon at the interface “graphene coating – quartz glass”, as well as on the surface of a round conducting particle. Such plasmons are of interest for creating sensor devices in medicine and biology due to the neutrality of graphene coatings. It is said that to increase the sensitivity of the sensor, the plasmon should be amplified. It has also been shown that the presence of conductive particles in the substance under study affects the overall refractive index of the substance and changes it even at the most insignificant concentration of additional substances (analytes).
