Lithium niobate‐based photonic sensor with Mach–Zehnder optical waveguide interferometer and tapered antenna array was designed and fabricated for measuring pulsed electric field with nanosecond risetime. The fabricated photonic sensor exhibits relatively flat frequency response with a variation not more than 4 dBm from 10 kHz to 5 GHz and minimum detectable electric field intensity of 0.4 V/m. A 10 3 V/m pulsed electric field with nanosecond risetime was also measured by this photonic sensor, the experimental results exhibit the information of electromagnetic pulse can be detected and extracted by this photonic sensor. © 2011 Wiley Periodicals, Inc.
