We propose and experimentally demonstrate an all-optical technique for separating a clock synchronization pulse from an optical time-division-multiplexed (OTDM) 100 Gb/s data packet. The technique is based on an all-optical switching device combined with optical feedback. This approach removes limitations found in other techniques such as those that are sensitive to long strings of zeroes in the data packet.
