The cost-effective, compact, and energy-efficient amplifier boasts a bandwidth of 300 nanometers, enabling it to transmit ten times more data per second.
I totally get how this would be useful in imaging systems, but I’m not understanding how it applies to communications.
The only thing I can think is perhaps carrying more modes through a multimode fiber? I never understood amplifier bandwidth to be a limiting factor, though.
What communications systems use a wide bandwidth of light (300nm is a LOT) into a single amplifier?
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.
That’s a great question. My guess is the bandwidth comes from bonding those extra modes and from the lower signal-noise ratio. That lower SNR means they could modulate with more sensitive but faster modes.

I wanna know if I can plug my guitar into it
