In periodically dispersion managed long-haul transmission systems, waveform distortion is
dominated by chromatic dispersion. As a result of the periodic waveform evolution, the …

We experimentally demonstrated a novel nonlinearity mitigation scheme based on digital
signal processing using a three-layer neural network (NN). 40-Gbit/s optical 16QAM signal …

Optical superchannels and digital nonlinear mitigation are key technology options to be
considered for the deployment of next-generation optical 400G transmission systems. In this …

We propose optical injection locking (OIL) to enable compensation of the inter-channel
nonlinear phase noise, which is dominated by cross-phase modulation (XPM). In this paper …
