Study and design of nanostructures on lithium niobate for dielectric material sensors: application in electrical insulation systems



Abstract. The measure, in industry, of voltage and electric field is essential for the design of insulation systems and this factor despite the performance of advanced numerical computation that allows only very difficult to estimate the electric field distribution disturbed by the presence of space charges. Indeed, the space charges distribution (an electron cloud located in a space which can be a vacuum, a gas, a liquid or a solid which can interfere with the movement of the electron flux flowing) depends poorly known physical factors such as mobility of the charged particles and also of the ionization rate of gas molecules. Therefore, it is necessary to measure precisely the intensity of the electrical field for more efficiency and reliabilities operations on high voltage systems. The development of nanotechnology, microelectronics and integrated optics (realization of all optical components on a single substrate) led to the birth of the electrical field optical sensors. The electric field sensors using the E/O effect can be divided into two categories: low-field sensors and high-field sensors. In this context, we studied the optical and electro-optical properties of this material; Then, geometric shapes and configurations (for crystal) are studied in order to choose which is most appropriate for a given application.
