From the abstract: "we obtained a continuous-wave gain bandwidth of 330 nm in the near-infrared regime. [...] Furthermore, we realized wide all-optical wavelength conversion of single-wavelength signals beyond 100 Gbit s−1 without amplifying the signal and idler wave."

Here is the paper: https://www.nature.com/articles/s41586-025-08824-3

I think figure 4 from the PDF shows it the best. Their amplifier covers 1400 nm to 1700 nm infrared lasers.
