TL;DR: Any application of an optical-frequency source could benefit from the high-precision optical synthesis presented here, and leveraging high-volume semiconductor processing built around advanced materials could allow such low-cost, low-power and compact integrated-photonics devices to be widely used.

TL;DR: In this article, the authors review the latest developments in this platform, examine where further development is necessary to achieve more functionalities in LNOI integrated optical circuits and make a few suggestions of interesting applications that could be realized in the platform.

TL;DR: In this article, the authors show how to synthesize the absolute frequency of a lightwave signal, using integrated photonics to implement lasers, system interconnects, and nonlinear frequency comb generation.

TL;DR: In this article, a periodically poled lithium niobate (LN) waveguide was applied directly to the thin-film LN for quasi-phase matching by a new surface poling technology.

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.
