Optical Clock Distribution Using A Mode-Locked Semi-Conductior Laser Diode System
Peter J. Delfyett, Davis H. Hartmann and S. Zuber Ahmad
Optical clock distribution has been achieved by using a modelocked semiconductor laser diode system as the master timing device. The optical clock has demonstrated a fanout of 1024, while maintaining less than 12 psec of jitter on the recovered clock signal for periods of over one hour. This type of clock distribution technique demonstrates a method to overcome fundamental problems associated with conventional electronic clock distribution techniques.
