Abstract

Recently the experiments demonstrating the advantages of direct optical control of ferroelectric domain profiles have been carried out. Here we present our findings and detailed analysis on time dependence of the ferroelectric coercive field after domain inversion of the LiTaO₃ and LiNbO₃ crystals. We have investigated the mechanisms of light influence and possibilities of optical control of domain structures in ferroelectrics, in particularly the roles of the various internal field components, their origins and dynamic behavior following domain reversal. Our experiments have shown the possibility of direct optical control of domain patterning in ferroelectrics.
