We propose in this chapter an integrated optical electromagnetic field sensor suitable for sensing in the Fresnel region over a wide frequency range. This device, based on a coherent symmetric interferometer implemented on LiNbO3 substrate, yields minimal coupling with critical radiating structures and enables their near-field monitoring. The principle and technologies of this optical sensor are described and applications of more complex platforms based on the optical device are discussed.

Abstract
We propose in this chapter an integrated optical electromagnetic field sensor suitable for sensing in the Fresnel region over a wide frequency range. This device, based on a coherent symmetric interferometer implemented on LiNbO3 substrate, yields minimal coupling with critical radiating structures and enables their near-field monitoring. The principle and technologies of this optical sensor are described and applications of more complex platforms based on the optical device are discussed.File in questo prodotto:
