摘要
The invention provides a generator (100) of a CS-RZ optical clock signal (H) at a predetermined clock frequency, the generator comprising:· a first laser source (1) and a second laser source (2) respectively producing first and second continuous lightwaves (s1, s2), the laser frequency of at least one of said sources (1) being adjustable;· coupling means (11) disposed to receive the first and second lightwaves (s1, s2) and suitable for forming optical beats (Sb) at a beat frequency; and· an opto-electronic feedback (101) to servo-control the adjustable-frequency laser source(s) (1) 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.
