Single-step Perturbation-based Nonlinearity Compensation of Intra- and Inter-Subcarrier Nonlinear Interference

We experimentally demonstrate a decision-directed, intra- and inter-subcarrier nonlinearity mitigation scheme based on first order perturbation. We achieve 0.9 dB Q2-factor improvement over linear compensation in a 200G dual-carrier PDM-16QAM transmission over 1200 km.
