Abstract
In a sychronizing arrangement for synchronizing two streams of optical pulses, the problem arises that for pulse frequencies above 10 GHz the operation of the synchronizing arrangement becomes increasingly difficult. To overcome that problem it has been proposed to use a phase locked loop having an optical phase detector, but prior art optical phase detectors have low efficiency and was rather complex. According to the invention an optically controlled optical switch is used as the phase detector.
