Abstract

It has been demonstrated [see, e.g., W.R. Babbitt and T. W. Mossberg, Opt. Commun. 65, 185 (1988)] that coherent optical processes can be employed to store and reproduce temporal sequences of optical data, thereby providing a mechanism for advanced optical memories. We find that excitation pulse phase noise can be used to extend the range of experimental conditions under which the storage process is effective and discuss the use of phase noise to achieve secure data storage.
