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 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: Using silicon nitride waveguides processed by plasma-enhanced chemical vapour deposition, full integration of ultrahigh-Q resonators with other photonic devices is now possible, representing a critical advance for future photonic circuits and systems.

TL;DR: In this paper, an integrated ridge resonator with a record Q factor over 200 million is presented, which brings performance that has been the exclusive domain of discrete silica and crytalline microcavity devices to integrated systems.

TL;DR: In this paper, the authors introduce design and fabrication techniques that allow analogous dispersion control in chip-integrated optical microresonators, and thereby demonstrate higher-order, wide-bandwidth dispersion over an octave of spectrum.
