@article{Joshi2017CounterrotatingCS, title={Counter-rotating cavity solitons in a silicon nitride microresonator.}, author={Chaitanya S. Joshi and Alexander Klenner and Yoshitomo Okawachi and Mengjie Yu and Kevin Luke and Xingchen Ji and Michal Lipson and Alexander L.

We demonstrate the generation of counter-rotating cavity solitons in a silicon nitride microresonator using a fixed, single-frequency laser. We demonstrate a dual three-soliton state with a difference in the repetition rates of the soliton trains that can be tuned by varying the ratio of pump powers in the two directions. Such a system enables a highly compact, tunable dual comb source that can be used for applications such as spectroscopy and distance ranging.
