Just a couple of new papers:
- Szabados, J. et al. Frequency Comb Generation via Cascaded Second-Order Nonlinearities in Microresonators. Phys. Rev. Lett. 124, 203902 (2020).
- Corcoran, B. et al. Ultra-dense optical data transmission over standard fibre with a single chip source. Nature Communications 11, 2568 (2020).
And a three more below which might be of interest.
