Recent developments in chip-based nonlinear photonics offer the tantalizing prospect of
realizing many applications that can use optical frequency comb devices that have form …

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 …

The generation of Kerr frequency combs in a coherently driven nonlinear microresonator is
now extensively investigated more generally by the research community as a potentially …

We demonstrate broadband frequency comb generation in the mid-infrared (MIR) from 2.3 to
3.5 μm in a Si_3N_4 microresonator. We engineer the dispersion of the structure in the MIR …

We report, to the best of our knowledge, the first demonstration of thermally controlled soliton
mode-locked frequency comb generation in microresonators. By controlling the electric …

Optical solitons are propagating pulses of light that retain their shape because nonlinearity
and dispersion balance each other. In the presence of higher-order dispersion, optical …

Microresonator frequency combs can be an enabling technology for optical frequency
synthesis and timekeeping in low size, weight, and power architectures. Such systems …

High-and ultrahigh-Q whispering-gallery mode resonators have the capability to trap
photons by total internal reflection for a duration ranging from nanoseconds to milliseconds …
