Cross-talk noise and storage density in holographic memory

We present a statistical analysis of the cross-talk limited storage capacity for both angle and wavelength multiplexed holographic memories. We obtain, for the first time, expressions for the storage capacity in terms of the number of bits per unit volume. It is found that it is reduced from the ultimate storage capacity of λ^-3 by a factor of the signal to noise ratio. The results also indicate that angle multiplexing has more degrees of freedom to be optimized to reduce the intrapage interpixel cross-talk noise
