Abstract
A Lithium niobate (LiNbO3) optical waveguide three-axis electric field sensor has been designed, fabricated, installed and measured. Experimental results reveal that the variation of the sensor frequency response is no more than ±3 dB from 100 kHz to 1 GHz. The output of the sensing system exhibits a linear function of the applied electric field varying from 2.2 kV/m to 56.8 kV/m. The time domain response of the sensor agrees well with the incident electric field. All these results demonstrate that the proposed sensor has a possibility to be used to detect the intense electromagnetic pulse (EMP) field.
