PLZT thin-film channel waveguides have been successfully formed in ridges by an ion-beam etching process. The electrooptic Kerr coefficients of the waveguides have been newly obtained. We have determined that the electrooptic coefficients R11′ and R12′ were 0.1–0.2 × 10−16 (m/V)2 and 0.01 × 10−16 (m/V)2, respectively, by Mach-Zehnder interferometric ...

PLZT electrooptic shutters: applications
Applied Optics, 1975This paper describes advances in the development of several electrooptic shutter devices utilizing the quadratic electrooptic effect of lead lanthanum zirconate titanate (PLZT) ceramic wafers. Aperture sizes utilized in these PLZT devices ranged from 25 microm to 0.25 m.

Abstract Spectra, kinetics and thermal behavior of photoluminescence in PLZT X/65/35 ceramics have been studied with respect to different concentrations of different sorts of defects (inherent: lead and oxygen vacancies and dopant-induced by Mn, Fe, Co, Ni). The features observed are shown to be related to disordering of the material.

Proceedings of 1994 IEEE International Symposium on Applications of Ferroelectrics, 2002
The local structure of PLZT has been examined by the means of neutron-powder-diffraction derived pair-distribution function (PDF). We find that atoms are displaced from the average periodic structure by a significant amount. The directions and magnitudes of the atomic displacements in PLZT are very similar to those found in PMN.

Matrix panels with excellent drive capability are fabricated by using a hot-pressed PLZT (7.9/70/30) ceramic plate. The matrix panel is 24×32 mm2 in area and 200 µm in thickness. On each surface, 30 transparent stripe electrodes are constructed perpendicular to the other face. For the transparent electrodes, sputtered indium tin oxide is used. To drive

Abstract Optical properties of PLZT(8/70/30) in various phases were studied by using HAUP method. Ferroelectric phase was found to be optically. active. From this result, it was revealed that the point group of PLZT should be C3 in the rhombohedral system(ferroelectric phase).

Synthesis and morphology of electrospun PVA/PLZT composite and single phase PLZT nanofibers
Materials Science and Engineering: B, 2011Abstract Polyvinyl alcohol/lead lanthanum zirconate titanate (PVA/PLZT) composite nanofibers were prepared by the electrospinning method. The PLZT sol was prepared by using lead acetate trihydrate, titanium isopropoxide and zirconium propoxide molecular precursors based on sol–gel procedure.

Birefringent light scattering in PLZT ceramics
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 1991A model for visible light scattering in thin, ferroelectric ceramic plates is presented. This and other previously published models are compared with experimental results. An expression for scattered light intensity over exit angle is developed on the basis of multiple refraction from randomly oriented grain and domain walls in a birefringent medium ...

Holographic correction of aberrations using PLZT
Applied Optics, 1988We describe the aberration correction capabilities of a holographic recording device made of antiferroelectricphase (7.6/70/30) ion-implanted lead lanthanum zirconate titanate. After a review of holographic aberration correction and a description of the device's holographic storage mode, we describe the experiment used to store a hologram which reduced
