Abstract
A fiber-optic sensing apparatus is provided, including an outer sleeve, an optical fiber sensor arranged within the outer sleeve, and a filling medium. The optical fiber sensor is capable of detecting a change of a refractive index or a change of surface plasmon waves over an outer surface of the outer sleeve. The filling medium may have a matching refractive index with the outer sleeve and with the optical fiber sensor. The outer sleeve may be exposed directly to the outside medium, or may be coated with at least one functional film layer such as a surface plasmon resonance (SPR)-active base film layer, or a reactive film layer that is reactive to a target molecule in the outside medium.
