Ultra-dense optical data transmission over standard fibre with a single chip source.

ABSTRACT: Micro-combs - optical frequency combs generated by integrated micro-cavity resonators - offer the full potential of their bulk counterparts, but in an integrated footprint. They have enabled breakthroughs in many fields including spectroscopy, microwave photonics, frequency synthesis, optical ranging, quantum sources, metrology and ultrahigh capacity data transmission. Here, by using a powerful class of micro-comb called soliton crystals, we achieve ultra-high data transmission over 75 km of standard optical fibre using a single integrated chip source. We demonstrate a line rate of 44.2 Terabits s^-1 using the telecommunications C-band at 1550 nm with a spectral efficiency of 10.4 bits s^-1 Hz^-1. Soliton crystals exhibit robust and stable generation and opera
