Abstract :
We measured the optical polarization dependence of the EO effect in epitaxial PLZT films. Mainly, polar nano-region switching causes optical polarization dependence of the EO effect. We fabricated a PLZT beam deflector and assembled an optical switch with 8times8 channels and less than 1-mus switching speed.
