Analytical estimates of the characteristics of surface plasmon resonance fibre-optic sensors

摘要

In surface plasmon resonance (SPR) fibre-optic sensors, the optical power transmittance is important in determining behaviour. In this paper numerical calculations are used to estimate the optical power transmittance of SPR fibre-optic sensors. These analytical estimations can be applied in SPR fibre-optic sensors both with a transducing layer and without a transducing layer. The results of these numerical calculations agree well with previously published experimental results. This work will aid in the design of SPR fibre-optic sensors in terms of geometrical structure, materials and dynamic range as well as allowing the prediction of performance and of limitations of the design.
