Materials for Phase Holographic Storage

Abstract

This report describes the recording, erasure, and fixing behavior of Fe-doped LiNbO3 at elevated temperatures and development of methods to improve the material performance. The major results of this study were: (a) The drift-like nature of the recording process at elevated temperatures was confirmed and a model to explain this effect was developed from studies of the bulk photovoltaic effect; (b) A model for the hologram erasure process at elevated temperatures was developed and tested; (c) The identification of Si as a mobile ionic species which may contribute to the fixing of holograms in Fe-doped LiNbO3. (d) The discovery that in Mn-doped LiNbO3 the recording sensitivity increases by a factor of fifty at 120C as compared with that at room temperature. These results have led to an understanding in detail of the mechanisms of hologram storage in LiNbO3.
