Symmetry properties of the converse piezoelectric effect are investigated for their use in fiber-optic sensing of individual electric field components. Three basic sensor designs are analyzed in detail. Suitable sensor materials are identified and relevant material properties are discussed. The sensitivity of the sensor to a specified field component is experimentally verified. A dynamic range of approximately 5 orders of magnitude is found for frequencies in the kilohertz range. The sensor concept is compared to electrooptic sensors.
