In this paper, a new method for generating tunable high-repetition-rate temporal cavity solitons (TCSs) using dual Brillouin laser pulses is reported. This method is more feasible than generating solitons via a continuous optical-driven nonlinear cavity because of the enhanced four-wave mixing process triggered by the high peak intensity Brillouin laser pulses. The generated TCSs can be directly tuned all-optically by locking to the beating signal arriving from dual Brillouin pulses.
In this paper, we report a new method to generate tunable high-repetition-rate temporal cavity solitons (TCSs) in a nonlinear fiber cavity, which is driven by dual Brillouin laser pulses. This method is more feasible than generating solitons via a continuous optical-driven nonlinear cavity because of the enhanced four-wave mixing process triggered by the high peak intensity Brillouin laser pulses. The generated TCSs lock to the beating signal arriving from dual Brillouin pulses, which allows the repetition rate of the solitons to be directly tuned all- optically. The TCSs can be continuously tuned over a repetition rate range of 140 similar to 242 GHz by controlling the external dual-wavelength spacing, and the pulse duration can be accordingly adjusted from 0.9 ps to 513 fs. Such TCSs with tunable high-repetition-rate can provide a practical solution for the low-noise controllable millimeter-wave and terahertz sources.
