INTER-RESONANCE SOLITON GENERATION AND TRAPPING

We show a new type of actively mode-locked fiber laser that, despite t he 2.5-km-long cavity and the average group-velocity dispersion of -20 ps(2)/km, generates solitons with duration of 2 divided by 4 ps, 1-GH z repetition rate and timing jitter of 0.7 ps, Such short solitons are generated in an inter-resonance condition that favors a highly stable propagation regime. Soliton duration and timing jitter are both contr olled by the self-frequency-modulation due to the background radiation emitted by the solitons themselves.
