Abstract

Holographic recording for data storage typically utilizes angular multiplexing for effectively accomplishing a 3d packing of data in the media. For large storage systems this results in very complex optical paths. Multiplexing by employing an orthogonal set of phase encoded references is an elegant answer to this problem. The results of experiments where as many as forty holograms are multiplexed in an SBN crystal using this technique are reported. Efficiency versus number of pages for different write times and crosstalk for various configurations is shown.
