Abstract

Parallel error decoding is discussed for 2D page access optical memory. Both parallel space- domain and parallel spectral-domain Reed-Solomon decoders are discussed and compared with conventional serial decoding implementations. The parallel approach is found to yield information rates of nearly 10¹² bps. A methodology is also presented for 4f optical storage system design. This approach allows the photorefractive crystal volume to be minimized while maintaining the maximum storage capacity that is consistent with a given SNR requirement.
