Abstract

This entry reviews the properties of the most important materials, such as ferroelectric and nonferroelectric crystals, ceramics, and semiconductors. It includes an exhaustive presentation of the physical and electro-optic (EO) properties of another important class of materials: the polymers and the liquid crystals (LCs). The remarkable EO properties of LC materials widely contribute to the development of flat-display technologies, which now have an immense industrial impact in the consumer market. Other original applications are emerging: the use of periodically poled EO crystals for efficient nonlinear frequency conversion, the photorefractive holography for information processing, and beam control and crystals having periodical nanostructuration that exhibit photonic bandgap properties for potential signal-processing applications. They will provide a new class of passive and active photonic circuits with unusual characteristics in the future.
