Ultrahigh-repetition-rate bound-soliton fiber laser

Ultrahigh-repetition-rate (over 100 GHz) bound-soliton pulses were experimentally generated in a fiber laser. Through incorporating a Loyt-type filter made of a piece of high birefringent fiber and an intracavity polarizer in a fiber laser, we found that not only ultrahigh-repetition-rate single-pulse soliton but also bound-soliton trains could be generated. Numerical simulations confirm the experimental observations.
