Abstract :
An electric field sensor array using optical coherence modulation of light is proposed. The system consists of lithium niobate (LiNbO3) optical coherence modulator acting as electric field sensor. The main characteristics of coherence-modulated transmissions include the need to use broadband optical sources and integrated optics lithium niobate electro-optic retarders. Coherence-modulated systems have been studied in recent years as new potential high-speed optical links useful for point-to-point, local area networks, and bidirectional transmissions, at optical wavelengths around 1300 nm. The paper describes the experimental system and characterization of the electro-optic sensor for detection of sinusoidal electric fields.
