We investigate the performance of an evanescent-field fibre sensor made from standard single-mode optical fibre with a tapered cladding region, upon which a thin attenuating material coating is deposited. Our method involves calculating the supermodes of the complete core-cladding-coating-air structure locally at each point along the taper and studying the(More)
An optical fiber sensor for electric field and electric charge, based on the deflection of a small cantilever, has been developed. When the sensor head is placed in an electric field, induced charging produces deflection of the cantilever, which is measured using low-coherence, Fabry-Perot interferometry. The sensor has been used to measure the electric(More)
