Paper Abstract

The paper describes an evanescent wave sensor model operating far from the modal steady state. Assuming that of the numerical aperture varies exponentially with the fibre length and the light losses are proportional to the local and fibre numerical apertures ratio, the sensor description was evaluated. Experiments, in which the sensor absorbance versus the refractive index of the medium surrounding the fibre core and the fibre sensing section length, were made to confirm the theoretical model of the sensor and good agreement was observed.
