| 摘要 |
The invention concerns a regenerator for transmission systems with solitons pulses, comprising a cavity laser, for instance a ring fibre laser, wherein is inserted a modulator (5), means for coupling the input signal to be regenerated in the modulator input (7), to ensure laser mode-locking, and means for coupling the regenerated signal in the modulator output (9). The soliton signal to be regenerated ensures the cavity laser locking-mode; moreover, the signal circulating in the cavity ensures a soliton signal modulation, which is thereby regenerated. Phase or intensity modulations, or both, can be used. The invention is characterised in that a ring cavity laser fibre, or a Fabry Perot cavity laser is used. The dispersion fibre non-linear loop mirror can be used as modulator, or an amplifier with semiconductor.
