Abstract :
A novel Mach-Zehnder interferometric wideband electric field sensing device utilizing the electro-optic effect is reported. Reverse poling of one arm of the interferometer allows for a response to common-mode electric fields. Because the lithium niobate sensor uses no metallic electrodes, there is only minimal disturbance to the field being measured.<>
