An integrated optical electric field sensor based on a Mach-Zehnder interferometer with the telescopic dipole is designed and fabricated, and its electrodes are segmented and connected with a telescopic dipole. The measured results show that when the frequency response is from 10 kHz to 6 GHz with the antenna length of 55 mm, the minimum detectable electric field of 20 mV/m can be obtained, and the linear dynamics range can reach 90 dB at 250 MHz.
