Recent investigations in holographic mass memory systems have produced proof-of-concept demonstrations that have highlighted their potential for providing unprecedented capacity, data transfer rates and fast random access performance (Heanue et al. 1

Photorefraction is a nonlinear optical effect in which large nonlinearities can be observed at relatively low optical power levels. This phenomenon has evolved from a laboratory curiosity to a useful device technology for optical information processi

We discuss the design of a complete, compact holographic storage demonstrator based on a combination of spatial and angular multiplexing and using acousto-optic deflectors for rapid nonmechanical access. We also describe the implementation of this de

The cross-talk noise in reconfigurable interconnection, which results from the nonuniform amplification in photorefractive two-wave mixing in the Fourier domain, in which maximum energy efficiency can be achieved, is considered. Both theoretical and

Self-oscillations in nonlinear optical four-wave mixing and resonators are considered. Some unique properties of these oscillations can be employed for implementing parallel optical thresholding, comparing, and maximum operations. Both theoretical an

We consider the noise gratings formed while writing angularly multiplexed holograms in photofractive media using a multiple exposure schedule. During the recording process of the pth exposure, the writing beams generate new gratings while erasing the

We describe a shift-invariant optical correlator with a volume hologram as a matched filter. Shift-invariance is achieved by the combination of degeneracy in one direction and image shifting in the perpendicular direction. The amount of shift-invaria

We analyze the unique statistics of complex amplitude noise in holographic data storage and determine the corresponding bit-error rate. Explicit expressions of the signal-to-noise ratio, the threshold value that distinguishes binary bits, and the bit
