Abstract
The invention provides a regenerator for very high rate solitons, the regenerator comprising a non-linear loop mirror or NOLM receiving the soliton signal and modulating it with a control signal. The regenerator also comprises a device for generating the control signal by beats between two light sources, with the frequency of at least one of the two sources being variable and servo-controlled as a function of the modulated soliton signal, e.g. as a function of its power, or servo-controlled by means of an optical phase-lock loop. This provides a soliton regenerator in which the electronic components operate at low frequency only, while being capable of regenerating a soliton signal at a very high rate.
