TLDR
Optical frequency comb generation from high-quality-factor AlN microring resonators integrated on silicon substrates is reported by engineering the waveguide structure to achieve near-zero dispersion at telecommunication wavelengths and optimizing the phase matching for four-wave mixing.Abstract:
Aluminum nitride (AlN) is an appealing nonlinear optical material for on-chip wavelength conversion. Here we report optical frequency comb generation from high-quality-factor AlN microring resonators integrated on silicon substrates. By engineering the waveguide structure to achieve near-zero dispersion at telecommunication wavelengths and optimizing the phase matching for four-wave mixing, frequency combs are generated with a single-wavelength continuous-wave pump laser. Further, the Kerr coefficient (n2) of AlN is extracted from our experimental results.read more

Dissipative Kerr solitons in optical microresonators
TL;DR: In this article, the discovery and stable generation of temporal dissipative Kerr solitons in continuous-wave (CW) laser driven optical microresonators is described and analytical and numerical descriptions are presented that do not only reproduce qualitative features but can also be used to accurately model and predict the characteristics of experimental systems.

Battery-operated integrated frequency comb generator.
TL;DR: A chip-based integration of microresonators and lasers produces a battery-powered comb generator that does not require external lasers, moveable optics or laboratory set-ups and should enable production of highly portable and robust frequency and timing references, sensors and signal sources.

TL;DR: In this article, surface roughness was exploited to achieve high quality factor (Q) and high confinement in Si3N4 ring resonators, achieving Q of 37 million for a ring of 2.5μm width and 67 million for an inner ring of 10μm.

Optical frequency metrology
TL;DR: The ability to count optical oscillations of more than 1015 cycles per second facilitates high-precision optical spectroscopy, and has led to the construction of an all-optical atomic clock that is expected eventually to outperform today's state-of-the-art caesium clocks.
