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 …

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 …

We demonstrate an approach for automated Kerr comb generation in the normal group-
velocity dispersion (GVD) regime. Using a coupled-ring geometry in silicon nitride, we …

Laser interferometry serves a fundamental role in science and technology, assisting
precision metrology and dimensional length measurement. During the past decade, laser …

Microcavities enable the generation of highly efficient microcombs, which find applications in
various domains, such as high-precision metrology, sensing, and telecommunications. Such …

Temporal cavity solitons (CSs) are pulses of light that can persist in coherently driven
passive resonators, such as fiber ring resonators and monolithic microresonators. It has …

We report on the experimental observation of coherent cavity soliton frequency combs in
silica microspheres. Specifically, we demonstrate that careful alignment of the microsphere …

We experimentally and theoretically investigate the dynamics of microresonator-based
frequency comb generation assisted by mode coupling in the normal group-velocity …

We show that an optical analog of Cherenkov radiation (dispersive wave) is observable in a
nonlinear microring resonator generating Kerr frequency comb and containing linearly …

We propose a new type of broadband and low repetition rate (RR) frequency comb
generator that has the shape of an elongated and nanoscale-shallow optical bottle …
