Abstract

A lithium niobate (LiNbO₃ )-based integrated optical sensor with Mach-Zehnder optical waveguide interferometer and tapered antenna array was designed and fabricated for electric field detection. Experimental results reveal that this sensor has a frequency response deviation less than ±10 dB within the range of 10 kHz to 18 GHz, and its minimum detectable electric field intensity is 0.4 V/m. Moreover, a pulsed electric field with nanoseconds width and electric field intensity of 103 V/m have been detected by this sensor.
