Persistent Spectral Hole-Burning Applications in Distributed Data-Storage and Processing
Brief review of zero-phonon lines, persistent spectral hole burning (PSHB) and its applications is given. The provided by PSHB additional dimension - the spectral one in optical data storage allows- n principle to get densities up to 10(12) bit cm-2 or 10(16) bit cm-3. In both cases an 10(-16) cm-3 cell comprising on average only 100 impurity molecules is involved to store a bit. It is a two small amount because of fluctuations in the distribution of impurities over the cells. Parallel processing and distributed data storage, realized in PSHB holography and optical modelling of neural networks, are prospective to utilize the full capacity of PSHB storage and processing.
