Optical frequency combs offer an unrivalled degree of frequency measurement precision
that underpins the advance of modern technology in both fundamental science and …

Over the past decade, the demonstration of frequency combs has been reported in a wide
range of quantum cascade lasers. These combs have huge potential in applications …

In many disciplines, states that emerge in open systems far from equilibrium are determined
by a few global parameters,. These states can often mimic thermodynamic equilibrium, a …

Laser cavity-solitons can appear in a microresonator-filtered laser when judiciously
balancing the slow nonlinearities of the system. Under certain conditions, such optical states …

High-quality optical ring resonators can confine light in a small volume and store it for
millions of roundtrips. They have enabled the dramatic size reduction from laboratory scale …

Soliton microcombs constitute chip-scale optical frequency combs, and have the potential to
impact a myriad of applications from frequency synthesis and telecommunications to …

Dissipative Kerr solitons are self-organized optical waves arising from the interplay between
the Kerr effect and dispersion. They can form in nonlinear microresonators by deliberately …

Optical frequency-comb sources, which emit perfectly periodic and coherent waveforms of
light, have recently rapidly progressed towards chip-scale integrated solutions. Among them …

In many laser systems, frequency combs whose output is frequency-modulated (FM) can
form, producing light whose frequency sweeps linearly. While this intriguing result has been …

Synthetic lattices in photonics enable the exploration of light states in new dimensions,
transcending phenomena common only to physical space. We propose and demonstrate a …
