Longitudinal electrooptic effects in slim-loop and linear PLZT ceramics

The longitudinal mode of operation was investigated in slim-loop PLZT 9, 10/65/35 and linear 12/40/60. Both birefringent and scattering effects were studied, using the strain-biasing technique for display applications. The results reveal strong dependence of birefringence on electric field in slim-loop materials in the presence of compressive strain and the existence of a threshold value for the field magnitude. Scattered light intensity was found to depend on stress and electric field. A similarity between the longitudinal and transverse effects in linear material was found. The feasibility of using these effects in display devices is presented.
