An interview with Pascal Del’Haye, the first author of the original Nature paper on Kerr frequency combs and now a group leader at the National Physical Laboratory (NPL) in Teddington by London. We talked about the first Kerr frequency combs, the following twelve years, the spirit of fundamental research, problems with names and more.
There are quite a few interesting papers that appeared over the last seven days. On Kerr frequency combs but also on closely related topics.
- Niu, R. et al. Repetition rate tuning of soliton in microrod resonators. arXiv:1809.06490 [physics] (2018).
- Wang, C., Zhang, M., Zhu, R., Hu, H. & Loncar, M. Monolithic photonic circuits for Kerr frequency comb generation, filtering and modulation. arXiv:1809.08637 [physics] (2018).

Some more papers that do not feature Kerr frequency combs but either Kerr cavity solitons, microresonators or integrated photonics are listed below.
Just a week after FiO, another conference starts next Sunday, the European Conference on Optical Communication (ECOC) 2018 in Rome. By now the program is out so let’s have a look:
Tuesday, 23 September:

New last week: one publication on Kerr frequency combs and one review on nonlinear effects in microresonators in general:
- Li, Y., Jiang, X., Zhao, G. & Yang, L. Whispering gallery mode microresonator for nonlinear optics. arXiv:1809.04878 [physics] (2018).
- Bendahmane, A., Fatome, J., Finot, C., Millot, G. & Kibler, B. Selective generation of Kerr combs induced by asymmetrically phase-detuned dual pumping of a fiber ring cavity. Opt. Lett., OL 43, 4449–4452 (2018).
And the [download id=”898″].
And below one paper on a low-power conventional frequency comb source published in the first issue of the new OSA Continuum journal.
This weekend the FiO (Frontiers in Optics) conference starts in Washington DC. So it is time to have a look at this year’s program and what’s in it for people interested in Kerr frequency combs. Here we go:

At least judged by recent publications, the work on Kerr frequency combs combined with a bit of second order nonlinearity is really taking off these days. Two more manuscripts related to Kerr frequency combs but where the Pockels effect plays a role as well:
- Xue, X., Zheng, X. & Zhou, B. Soliton regulation in microcavities induced by fundamental-second-harmonic mode coupling. Photon. Res., PRJ 6, 948–953 (2018).
- Gong, Z. et al. High-fidelity cavity soliton generation in crystalline AlN micro-ring resonators. Opt. Lett., OL 43, 4366–4369 (2018).
And the [download id=”886″].
And in case you were always thinking that the spacing of Kerr frequency combs is too big, something relevant below.
Only one new paper on Kerr frequency combs and their soliton dynamics and one paper that is somewhere in between second and third order nonlinearity:
- Yi, X., Yang, Q.-F., Yang, K. Y. & Vahala, K. Imaging soliton dynamics in optical microcavities. Nature Communications 9, 3565 (2018).
- Mosca, S. et al. Modulation Instability Induced Frequency Comb Generation in a Continuously Pumped Optical Parametric Oscillator. Phys. Rev. Lett. 121, 093903 (2018).
And the [download id=”880″].
And below two more papers on more second order nonlinear effects in optical microresonators and resonant EOM combs.
