Electro Optic Characteristics of PLZT Ceramics Fabricated by Two Stage Sintering Method

ABSTRACT

PLZT ceramics of composition La/Zr/Ti=X/65/35(X=5-10 at.%) were fabricated by two state sintering technique.Transparent PLZT ceramics were obtained in the composition above 8 at. % La. Variations of electrooptic properties in the compositions between 8 at. % and 9 at. % La were able to be expected from the significant differences of P-E hysteresis curve and the changes of dielectric phase transition. The range of birefringence of 8/65/35 specimen was 4.08${times}$10-3. Domain switching of 9/65/35 specimen was agreed with the applied electric pulse because input pulse signal corresponds to optical pulse response.
