Paper Abstract

On the basis of theory of electromagnetic field theory and fiber grating technology, a practical sensor of electric current is reported in this paper. The Bragg wavelength shift is linear to the electric current intensity, and the range of linear tuning is about 1.0 nm. The sensitivity of electric current sensor is up to 11.696 A/nm. The formulas have been derived theoretically, and the experimental results accord with the theoretical calculations.
