摘要：

A new configuration for a Mach-Zehnder interferometric electric field sensor device utilizing the electrooptic effect is reported. The lithium niobate device uses no metallic electrodes and operates solely by immersion in an electric field. Reverse poling of one arm of the interferometer provides opposing optical phase changes in the two interferometer arms when placed in an electric field. One fabricated device exhibits a measured minimum detectable field of 0.22 V/m square-root Hz and a frequency response of greater than 1 GHz. Theoretical calculations show that detection of 0.11 V/m square-root Hz is attainable while the upper frequency limit can exceed 6 GHz.
