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

In previous investigations of optical data storage in persistent spect ral-hole-burning materials, either the spectral or the temporal positi ons of the data were used as memory addresses. We suggest having the a ddress represented by the spectral shape of the writing field and retr ieving information with the aid of pattern recognition of this spectra l shape. This procedure is expected to accelerate access to the stored data. To evaluate the validity of the method, we consider various phy sical effects that may give rise to cross talk among the different add resses. A numerical simulation under realistic conditions is presented .
