BACKGROUND The generation and control of coherent electromagnetic waves, such as
those provided by electronic oscillators in the radio frequency domain or lasers in the optical …

Optical frequency combs were developed nearly two decades ago to support the world's
most precise atomic clocks. Acting as precision optical synthesizers, frequency combs …

The quest towards the integration of ultra-fast, high-precision optical clocks is reflected in the
large number of high-impact papers on the topic published in the last few years. This interest …

Over the past decade, optical frequency combs generated by high-Q microresonators, or
optical microcombs, which feature compact device footprints, low power consumption, and …

This chapter describes the discovery and stable generation of temporal dissipative Kerr
solitons in continuous‐wave (CW) laser‐driven optical microresonators. The experimental …

Optical atomic clocks represent the state of the art in the frontier of modern measurement
