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 …

Gallium phosphide (GaP) is an indirect-bandgap semiconductor used widely in solid-state
lighting. Despite numerous intriguing optical properties—including large χ (2) and χ (3) …

Self-organized solitons confined to an optical resonator would offer unique capabilities for
experiments in communication, computation and sensing with light. Here, we report the …

Femtosecond laser-based generation of radio frequency signals has produced astonishing
improvements in achievable spectral purity, one of the basic features characterizing the …

The generation of spectrally pure microwave signals is a critical functionality in fundamental
and applied sciences, including metrology and communications. Optical frequency combs …

Temporal dissipative solitons in a continuous-wave laser-driven nonlinear optical
microresonator were observed. The solitons were generated spontaneously when the laser …

Continuous-wave laser-driven, high-Q Kerr–nonlinear optical microresonators have enabled
the generation of optical frequency combs, ultralow-noise microwaves and ultrashort optical …

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 …
