Electronic interfaces for optical packet switching and routing

We demonstrate novel electronic circuits to identify, route and solve contention between optical packets having frequency tone header. The detection processing times of the electronic circuits are very short, the header recognition circuit (HRC) response time itself is 40 ns and the logical decision circuit (LDC) is 40 ns, too. Both circuits use fast TTL technology. The switching, routing and contention solution is performed packet-by-packet without degradation or loss of packets. This system is applicable to future photonic switch with all-optical packets network.
