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 …

The experimental realization of a Kerr frequency comb represented the convergence of
research in materials, physics, and engineering. This symbiotic relationship continues to …

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 …

Microresonator frequency combs harness the nonlinear Kerr effect in an integrated optical
cavity to generate a multitude of phase-locked frequency lines. The line spacing can reach …

Optical soliton molecules are bound states of solitons that arise from the balance between
attractive and repulsive effects. Having been observed in systems ranging from optical fibres …

Passive Kerr cavities driven by coherent laser fields display a rich landscape of nonlinear
physics, including bistability, pattern formation, and localized dissipative structures …

We report on experimental observations of coexistence and interactions between nonlinear
states with different polarizations in a passive Kerr resonator driven at a single carrier …

Abstract The Lugiato–Lefever equation is a cubic nonlinear Schrödinger equation (NLSEs)
that occurs as a model in nonlinear optics and includes dam**, detuning, and driving. On …

Dissipative Kerr solitons are localized structures that exist in nonlinear optical cavities. They
lead to the formation of microcombs—chip-scale frequency combs that could facilitate …

We theoretically study the generation of optical frequency combs and corresponding pulse
trains in doubly resonant intracavity second-harmonic generation (SHG). We find that …
