Paper Abstract

High density storage of data in photosensitive electrooptic crystals has been achieved. One of the crystals with the highest writing sensitivity is LiNb03 doped with iron. A key factor in its high sensitivity involves the nature of the charge transport in the crystal. A series of measurements has been carried out to study the charge transport by photocurrent measurements and electrooptic measurements. The two techniques are shown to give consistent results. When described in terms of an equivalent internal electric field a dependence on light intensity is required.
