In terms of industrial applications, the abstract states

We have realized all-optical wavelength conversion for a more than 200-nm-wide wavelength span at 100 Gbit s−1 without amplifying the signal and idler waves. As the 32-GBd 16-QAM is the dominant modulation format of current optical-fibre communication systems connecting the continents on Earth, the Si3N4-chip high-efficiency wavelength conversion demonstrated has a bright future in the all-optical reconfiguration of global WDM optical networks by unlocking transmission beyond the C and L bands of optical fibres and increasing the capacity of optical neuromorphic computing for artificial intelligence.
