Thermal fixing of 10,000 holograms in LiNbO3 : Fe

We discuss thermal fixing as a solution to the volatility problem in holographic storage systems that use photorefractive materials such as LiNbO3:Fe. We present a systematic study to characterize the effect of thermal fixing on the error performance of a large-scale holographic memory. We introduce a novel, to our knowledge, incremental fixing schedule to improve the overall system fixing efficiency. We thermally fixed 10,000 holograms in a 90 degrees-geometry setup by using this new schedule. All the fixed holograms mere retrieved with no errors. (C) 1999 Optical Society of America.
