| description | This paper presents a mathematical model of the sensitive element of a refractometric fiber-optic sensor the principle of
operation of which is based on the phenomenon of surface plasmon resonance. The sensing element design is a sequential
connection of a multimode fiber (MMF), a single-mode fiber (SMF), and a multimode fiber forming an MMF-SMF-MMF
structure. The SMF site is coated with a thin film of gold. To model the element, the approach used in calculating the
classical Kretschmann configuration for volumetric optical structures was applied. The refractive index of the fiber is
calculated based on the Sellmeyer equation, and the refractive index of the gold is determined using the Drude model.
The simulation results are compared with experimentally obtained transmission spectra of fabricated samples of sensing
elements. For approbation of the model, the sensing elements of fiber-optic sensors with the following parameters are
made: core diameter of multimode fiber 62.5 μm, core diameter of singlemode fiber 9 μm, coating SMF-segment with
50 nm gold film. Transmission spectra of fiber-optic sensor sensing elements in aqueous glucose solutions of various
concentrations were obtained. It is demonstrated that the proposed model describes well the experimentally obtained
transmission spectra of sensitive elements based on MMF-SMF-MMF structures in the region of surface plasmon
resonance. The proposed model can be used to optimize the design of the sensitive element of refractometric fiber-optic
sensors in order to increase the sensitivity. The proposed model implies its use in the development of an algorithm for
interrogation of sensing elements based on fiber MMF-SMF-MMF structures. |
