PHASE-ENCODING TECHNIQUE IN TIME-DOMAIN HOLOGRAPHY - THEORETICAL ESTIMATION

In previous investigations of optical data storage in persistent spectral-hole-burning materials, either the spectral or the temporal positions of the data were used as memory addresses. We suggest having the address represented by the spectral shape of the writing field and retrieving information with the aid of pattern recognition of this spectral shape. This procedure is expected to accelerate access to the stored data. To evaluate the validity of the method, we consider various physical effects that may give rise to cross talk among the different addresses. A numerical simulation under realistic conditions is presented.
