We introduce a novel all‐optical packet‐switching system using a terahertz optical asymmetric demultiplexer (TOAD) based on optical time‐division multiplexing (OTDM). Ultra‐fast packet switching is performed without undergoing optical‐to‐electronic conversion. An optical packet at 10 Gb/ps is generated with a high‐definition video signal. All‐optical packet‐level clock extraction for synchronization of the switch node is performed using a modified TOAD. The extracted packet‐level clock is used for detecting the header and the payload data. By integrating the above all‐optical processors, we set up a rack‐mounted all‐optical packet‐switching system and successfully demonstrate exchanging the video signals from the source to the destination. © 2006 Wiley Periodicals, Inc.
