TL;DR: In this paper, a semiconductor laser is stabilized to an optical transition in a microfabricated rubidium vapor cell, and a pair of interlocked Kerr-microresonator frequency combs provide fully coherent optical division of the clock laser to generate an electronic 22 GHz clock signal with a fractional frequency instability of one part in 1013.

TL;DR: In this article, a turnkey regime for soliton microcombs is demonstrated, in which solitons are generated by switching on a co-integrated pump laser, eliminating the need for photonic and electronic control circuitry.

TL;DR: In this article, a high Q factor of 260 million was achieved in an electrically pumped integrated laser with a corresponding short-term linewidth of 12'Hz and the same configuration was shown to relieve the dispersion requirements for microcomb generation that have handicapped certain nonlinear platforms.

TL;DR: A turnkey regime for soliton microcombs is demonstrated, in which solitons are generated by switching on a co-integrated pump laser, eliminating the need for photonic and electronic control circuitry.

TL;DR: In this article, a soliton microcomb was demonstrated in a monolithic high-Q LN resonator, where the LN soliton mode-locking process self-starts and allows bi-directional switching of soliton states.
