Electrooptic Properties of Ba, Sn, and La Modified Lead Zirconate Titanate Ceramics

Abstract

Electrooptic effects observed so far in ferroelectric lead zirconate titanate ceramic materials are transverse electrooptic effects (linear, quadratic, and memory), strain-biased longitudinal electrooptic memory effect, and electrically controlled scattering. The electrooptic memory effects are related to variations of ceramic birefringence with remanent polarization. All the above electrooptic effects are found in Ba, Sn, and La modified lead zirconate titanate ceramics except electrically controlled scattering. Both the character and magnitude of these effects are strongly dependent on the composition and grain size of the ceramic material as well as on the temperature and light wavelength of observation. The results for the La modified ceramics, which can be made highly transparent, are discussed in the greatest detail. The various electrooptic effects are shown to arise either from orientation of ferroelectric domains or from field-enforced ferroelectric distortion of certain para-electric materials.
