Three-Wave Trapponic Solitons for Tunable High-Repetition Rate Pulse Train Generation
Résumé
We demonstrate that the parametric mixing of an ultra-short Zakharov-Manakov (ZM) soliton pulse with a quasi-continuous wave (CW) signal in a weakly quadratic nonlinear and dispersive medium may lead to the generation of a three-wave soliton with variable speed, or trappon. We show that trappons may provide a novel mechanism of cavity-less ultra-short pulse train generation. The time width, the amplitude and the repetition rate of the generated pulse trains may be controlled in a stable manner by adjusting the intensity level of the CW signal and/or the ZM short soliton pulse.
