There seems to be no new publication on actual Kerr frequency combs using the third order nonlinearity but going one order down, there are two new publications:
- Szabados, J., Sturman, B. & Breunig, I. Frequency comb generation threshold in χ(2) optical microresonators. arXiv:2007.05287 [physics] (2020).
- Lobanov, V. E. Two-color flat-top solitons in microresonator-based optical parametric oscillators. arXiv:2007.06490 [nlin, physics:physics] (2020).
And below two more publications on offset detection of light and injection locking to microresonators.
- Yang, Y. et al. Light phase detection with on-chip petahertz electronic networks. Nature Communications 11, 3407 (2020).
- Galiev, R. R., Kondratiev, N. M., Lobanov, V. E., Matsko, A. B. & Bilenko, I. A. Optimization of Laser Stabilization via Self-Injection Locking to a Whispering-Gallery-Mode Microresonator. Phys. Rev. Applied 14, 014036 (2020).
