100-Gbps per-channel all-optical wavelength conversion without pre-amplifiers based on an integrated nanophotonic platform.

All-optical wavelength conversion based on four-wave mixing attracts intense interest in many areas, especially in optical fiber communications, due to the advantages of femtosecond response, modulation-format transparency, and high flexibility in optical network management. In this paper, we present the first optical translation of 32-GBaud 16QAM signals with an integrated SiN nonlinear nanophotonic waveguide. An on-chip continuous-wave conversion efficiency of up to -0.
