Kerr soliton generation by silicon nitride (SiN) andThe system integrates a silicon (Si) modulator, dispersion compensator, and receiver.WDM communication over single-mode fiber was demonstrated. 1.68Tbit/The transmission speed of 1.5 s was achieved, and dispersion compensation at 40 km SMF was reduced to 1/1 of that of commercial transceivers.The number of bits per second has been successfully reduced to 6. In the future, 10Tbit/The potential to achieve data rates in excess of 1.5 s is a significant advantage of this technology, and it is expected to be used in the future.It is expected to improve the efficiency of interconnection in data centers, etc.
