Abstract
The invention relates to the obtaining of a structure generating non-linear electrooptical effects, the effects being due to molecules or inter-molecular groupings possessing a non-linear susceptibility and the orientation of the molecules or groupings being induced by an applied electric field. According to the invention, the orientation of the molecules or inter-molecular groupings (5) is obtained by of a dielectric having a permanent polarisation such as an electret (6).
