Abstract

We developed a bit-oriented three-dimensional recording with a Ce-doped Sr0.75Ba0.25Nb2O6 (SBN:75) crystal. The ferroelectric polarization was reversed by a focused laser beam in a crystal with a temperature of 38 °C to form bit data. The recorded domain was stable at 15 °C. The data were read as the refractive-index change induced by spontaneous polarization through the Pockels effect. We wrote a single datum in SBN:75 crystal with ferroelectric-domain reversal and observed the domain image with a phase-contrast microscope. Numerical calculations to estimate the domain image were also performed. The observed results were in good agreement with the numerical expectations.
