An integrated electromagnetic field sensor using Z-cut LiNbO<sub>3</sub> Mach-Zehnder waveguide modulator and micro antenna was fabricated and measured. A coplanar waveguide antenna was directly integrated with the traveling-wave electrode of the Mach-Zehnder waveguide modulator on the same LiNbO<sub>3</sub> substrate. The minimum detectable electric field(More)
A new type electrooptical electromagnetic field probe was fabricated by combining three magnetic field sensors, each of which consists of a Mach-Zehnder modulator and an integrated annular antenna. The frequency response was flat from 50 MHz to 2.2 GHz. The average minimum detectable electromagnetic field intensity of the sensor is 2.22 mV/m. When the probe(More)
