Artificial Neural Networks for Linear and Non-Linear Impairment Mitigation in High-Baudrate IM/DD Systems

We propose using artificial neural networks onto IM/DD optical links to infer simultaneously the linear and non-linear channel response. We experimentally exploit this information on an 84-GBd 4-PAM system, proving up to 10x BER improvement over FFE after 1.5-km SSMF.
