Paper Abstract

This study suggests an optical fault-tolerant system using all-optical sensing and feedback circuits with photorefractive crystals. The first example is a fault- tolerant system in which the system independently detects a cutoff of the optical transmission line and converts its routing to the backup line. Next, while practical application of holographic optical memory is currently being developed, under proposing system, the memory system automatically detects the loss of information (dropout) in optical memory, and reloads and eventually restores the corresponding data from the backup memory.
