摘要：

Successful 50GHz operation of a phaselocked loop is demonstrated using four-wave mixing in a travelling-wave laser diode optical amplifier. A prescaled 6.3GHZ clock is recovered from a 50Gbit/s TDM optical signal using the 50GHz phase comparison output obtained as the crosscorrelation between a 50Gbit/s optical signal and a short (< 10ps) 6.3GHz optical clock pulse train in the generated four-wave-mixing light.
