ELECTROOPTIC PROPERTIES OF THE 2-STAGE SINTERED BA(LA1 2NB1/2)O-3-PB(ZR,TI)O-3 CERAMICS/

Transparent Ba(La1/2Nb1/2)O-3-Pb(Zr, Ti)O-3 electrooptic ceramics (BLN -PZT) were fabricated by the two-stage sintering method, and the optic al and electrooptic properties were investigated for various compositi ons. Refractive indices at 633 nm wavelength were about 2.4 for all co mpositions, and a high optical transmittance of more than 56% at 633 n m wavelength was observed for 9.0/65/35 composition. Linear and quadra tic electrooptic coefficients, tau(C) and R, were 6.01x10(-10) m/V and 10.535x10(-16) m(2)/V-2, respectively, for 9.0/50/50 and 9.0/55/45 co mpositions near the morphotropic phase boundary (MPB) region.
