Abstract :
We propose a novel temperature independent electric field optical sensor using fiber Bragg gratings (FBG) attached to a piezoelectric material. The deformation on the piezoelectric material due to the presence of the electric field causes variation of the reflected wavelength. To compensate the temperature variations we used two FBGs attached to two pieces of the same piezoelectric substrate configurations of fiber grating in parallel and series are also studied in this paper.
