Non-invasive vectorial electric field characterization with optical probes

This paper describes electric field sensors based on electro-optic technique. The principle is explained and the effect is optimized within a pigtailed electro-optic probe. The performances are fully evaluated, in terms of linearity, dynamics, vectorial selectivity, bandwidth and disturbance on the field to be measured. Some examples of application such as mapping of E-field in guided configuration are demonstrated.
