We report the first demonstration of all-optical address recognition and self-routing of photonic packets for a case where the packet bit period is only 4 ps, corresponding to a 0.25- Tb/s bandwidth optical network. An ultrafast all-optical devices, known as a terahertz optical asymmetric demultiplexer (TOAD), was used to read the address information encoded in a packet header, which in turn was used to route the packet. The bit-error rate at the switch output was measured to be less than 10-9.
