A novel and simple method is presented to generate a tunable high-repetition-rate pulse train based on dual-mode self-injection locking of a Fabry-Perot laser diode (FP-LD). Two fiber Bragg gratings (FBGs) are used in the experiment as feedback components. The two self-injection-locked modes evolve into a high-power, high-repetition-rate pulse train through the interplay between self-phase modulation and anomalous dispersion in a highly nonlinear fiber. A 139.6-GHz transform-limited pulse train with a peak power of 120 mW is generated. The pulsewidth is 1.7 ps, and the time-bandwidth product is 0.31. The repetition rate can be tuned by tuning the Bragg wavelengths of one of the two or both FBGs to coincide with other FP-LD modes. The output pulse is stable.
