The body of literature on Kerr frequency combs keeps growing. The latest three additions you can find below.
- Skryabin, D. V. & Kartashov, Y. V. Self-locking of the frequency comb repetition rate in microring resonators with higher order dispersions. Opt. Express, OE 25, 27442–27451 (2017).
- Wu, J. et al. Harnessing optical micro-combs for microwave photonics. arXiv:1710.08611 [physics] (2017).
- Yu, M., Okawachi, Y., Griffith, A. G., Lipson, M. & Gaeta, A. L. Microresonator-based high-resolution gas spectroscopy. Opt. Lett., OL 42, 4442–4445 (2017).
And the [download id=”487″]. It also includes two more papers which combine classical mode-locked lasers with microresonators below but which I would not classify as Kerr frequency combs. The references and links are given below.
