The device and method are based on tapping off a predetermined line signal fraction and inputting it, together with a continuous pumping radiation, to a resonant cavity which comprises a non-linear wave guide. The value of the pumping wavelength is related to the wavelength of the line signal pulses to produce therewith a four-wave mixing (FWM) effect in the non-linear wave guide. In travelling the non-linear wave guide, a clone signal is generated by FWM effect which duplicates the pulse sequence of the line signal at a clone wavelength. By adjusting the length of the resonant cavity such that, in inputting the line signal, each of its pulses will come in at exactly a pulse of the clone signal which is being circulated within the cavity, a clone signal can be circulated within the resonant cavity whose pulse sequence represents the optical clock signal sought.
