Abstract :
A novel entirely passive electro-optic electric field sensor is reported. This sensor is based on the intensity change of the diffracted light from an electro-optically induced Bragg grating in a periodically poled LiNbO3 device. This new type of electric field sensor is simple, inexpensive and capable of achieving high sensitivity, linear operation and very large bandwidth with stable intrinsic biasing
