Dispersion tailoring in wedge microcavities for Kerr comb generation [PDF]

, 2020
The shaping of group velocity dispersion in microresonators is an important component in the generation of wideband optical frequency combs. Small resonators - with tight bending radii - offer the large free-spectral range desirable for wide comb ...

Power-efficient generation of two-octave mid-IR frequency combs in a germanium microresonator

Nanophotonics, 2018
Octave-spanning frequency comb generation in the deep mid-infrared (>5.5 μm) typically requires a high pump power, which is challenging because of the limited power of narrow linewidth lasers at long wavelengths. We propose twofold dispersion engineering

On timing jitter of mode locked Kerr frequency combs

Optics Express, 2013
We study fundamental timing jitter in repetition rate of a mode locked Kerr frequency comb generated in an externally pumped nonlinear ring resonator. We show that the increase in the integrated power of the comb harmonics, and the corresponding decrease of the duration of the associated pulse, results in the increase of low frequency noise, and a ...

Raman-Kerr frequency combs in microresonators with normal dispersion

Optics Express, 2017
We generalize the coupled mode formalism to study the generation of frequency combs in microresonators with simultaneous Raman and Kerr nonlinearities and investigate an impact of the former on the formation of frequency combs and dynamics of platicons in the regime of the normal group velocity dispersion. We demonstrate that the Raman effect initiates
