Broadband Efficient Soliton Microcombs in Pulse-Driven Photonic Microresonators
Anderson, Miles; Bouchand, Romain; Obrzud, Ewelina; Obrzud, Ewelina; Liu, Junqiu; Karlen, Sylvain; Lecomte, Steve; Herr, Tobias; Kippenberg, Tobias J. (2019-05-05)Broadband single-soliton based frequency combs, with a detectable repetition rate of 28 GHz, are efficiently generated through pulse-driving of a chip-based Si3N4 microresonator. We observe an influence of the pulse-driving ... -
