Abstract

Periodicaly poled LiNbO₃ single crystals with antiparallel domain configurations have been successfully grown with a (010) oriented seed from a congruent melting composition with 4 mol % potassium addition using a modified Cz geometry. The experiments reported in this paper showed that the polarization antiparallel domain structure in lithium niobate crystals can be created during growth process by a direct poling technique with electric field of alternating polarity. PPLN strucutres with period length 20-100 μm were demonstrated by this method.
