Abstract

An integrated electromagnetic field sensor using Z‐cut LiNbO~3~ Mach–Zehnder waveguide modulator and microantenna 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~3~ substrate. The minimum detectable electric field strength is 8.91 × 10^−4^ V/m at 2 GHz. © 2007 Wiley Periodicals, Inc.
