Integrated combs drive extreme data rates - "A chip-based optical frequency comb source has now been successfully used to send 661 Tbits–1 over 9.6 km of multicore fibre, bringing considerable savings in the energy consumption and size of data transmission equipment"

A Nature Photonics article authored by Professor Blumenthal discusses the current state-of-art optical frequency comb-based approaches to satisfy optical fibre transmission demands for 'unprecedented bandwidths due to the explosive growth of video and Internet of Things.' This article can be viewed using the Springer Nature SharedIt link given here.
