Paper Abstract

Lithium niobate based (LiNbO3) integrated optical sensor with Mach-Zehnder optical waveguide interferometer and tapered antenna array was designed and fabricated for measuring pulsed electric field with nanosecond width. The fabricated sensor exhibits relatively flat frequency response with a variation not more than 4 dB from 10 kHz to 5 GHz and minimum detectable electric field intensity of 0.4 V/m. A 103 V/m pulsed electric field with nanosecond width was also measured by this integrated optical sensor, the experimental results exhibit the information of EMP can be detected and extracted by this integrated optical sensor.
