Photonic Electric Field Sensor Based on Polymeric Microspheres. Ali,Tindaro Ioppolo,Volkan. Otügen,Marc Christensen,Duncan MacFarlane3. Department of Electrical Engineering, Southern . This paper describes an electrode-less, all-optical, wideband electric field sensor fabricated in an electro-optic lithium niobate substrate. The operation of an all-fiber polarimetric electric field sensor based on nematic liquid crystal infiltrated photonic crystal fiber is demonstrated.

The transmission properties are studied for different lengths . Taylor, “ Advanced materials and device technology for photonic electric field sensors ,” Proc. At the sensor head the photonic energy is converted into electrical energy from which the active elements in the sensor head are supplied. The sensor head uses electrically small transducers to pick up the electric (E-) or magnetic (H-) fields.

This electrode- less, all optical, wideband electrical field sensor is fabricated using standard processing for E-O polymer photonic devices. We demonstrate an interferometric fiber-optic dc and low-frequency electric - field sensor based on the electrostrictive effect. Electric field sensing schemes, using Lithium Niobate (LiNbO 3) electro-optical retarders, are being studied since several years.
