Abstract:Recent patents and progress on all-optical binary pattern recognition using the passive correlator and all-optical
logic gates have been reviewed. The correlator is relative simpler and easy to be implemented, however the path number
of the correlator is dependent on the length of target pattern. In contrast, the pattern recognition system based on alloptical
SOA logic gates can be a promising alternative even for high bit-rate optical signals. It is shown that, the gate
count can be reduced dramatically when employing serial logical processing, which allows also reconfiguration capability
of the target patterns.
