Abstract :
The use of Ti:LiNbO3 symmetric and asymmetric Mach-Zehnder interferometric modulators with a push-pull lumped electrodes and a plate-type probe antennas to measure an electric field strength is described. The minimum detectable electric fields are ~1.84 V/m and ~11.6 V/m corresponding to a dynamic range of about ~22 dB and ~6 dB for a symmetry MZ, and 0.823 V/m and 5.19 V/m corresponding to a dynamic range of about ~29 dB and ~13 dB for an asymmetry MZ at frequencies 500 KHz and 5 MHz, respectively.
