In this paper the physical basis for the design of an optical fibre sensor suited for aqueous medium and gas phase based on the excitation of an evanescent wave at the core/cladding interface is developed. The detection based on the refractive index changes of the infinite dielectric medium, sol-gel polymer, deposited on the uncladed part of the fibre. Refractive indices of absorbent, fuel and unleaded gas were determined. Using a xerogel sensing layer as optical cladding, toluene detection in water was performed. The detection limit is 1 per cent (in volume) toluene in water.
