Abstract

We have developed a bit-oriented three-dimensional domain memory with a photorefractive crystal. A Ce-doped SBN is used to record a bit data. The ferroelectric polarization is reversed by a focused laser beam in a crystal with the temperature at 38 degrees Celsius to form a bit data. The recorded domain is stable at 15 degrees Celsius. The data is read as the refractive index change induced by spontaneous polarization via Pockels effect. We show the domain image observed with phase contrast microscope. We also show the computer simulated images. The result in experiment is in good agreement with the simulated result.
