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 …

Dissipative Kerr solitons in resonant frequency combs offer a promising route for ultrafast
mode-locking, precision spectroscopy and time-frequency standards. The dynamics for the …

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 …

Optical frequency combs, which emit pulses of light at discrete, equally spaced frequencies,
are cornerstones of modern-day frequency metrology, precision spectroscopy, astronomical …

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 …

Laser frequency combs are enabling some of the most exciting scientific endeavours in the
twenty-first century, ranging from the development of optical clocks to the calibration of the …
