Abstract
Summary form only given. Quasi-phase-matching (QPM) of ferroelectric crystals with periodically 180/spl deg/ inverted domain structures has emerged as an important technology for nonlinear frequency generation. We report a use of transient current analysis to investigate the kinetics of polarization switching in congruent grown Z-cut lithium niobate (LiNbO/sub 3/) at various field strength and poling direction. Our study indicates the axial anisotropy and the linear dependence of switching current and 1/switching time on E are due to a field-driven sidewise 180/spl deg/ domain motion.
