ABSTRACT:
The present invention provides a generator of a CS-RZ optical clock signal at a predetermined clock frequency. The generator contains a first laser source and a second laser source which respectively produce first and second continuous lightwaves, where the laser frequency of at least one of the sources is adjustable. The generator also contains a coupler disposed to receive the first and second lightwaves and forms optical beats at a beat frequency. An opto-electronic feedback is used to servo-control the adjustable-frequency laser source(s) in such a manner that the beat frequency, which is equal to the difference between the laser frequencies, is substantially equal to the clock frequency.
