Additional information

This study established that even if such deterministic inter-channel nonlinear interactions are ideally compensated, the system capacity remains restricted by parametric noise amplification. The paper provides both analytical and numerical predictions, and easily calculable hard limits which have yet to be exceeded (even in phase conjugate twin waves which readily cancel inter channel effects - doi:10.1038/nphoton.2013.109 in Nature). The paper has enabled industry to avoid development of multi-channel nonlinear compensators. Also led to research forming Prof Ellis’ contribution to the EPSRC project UNLOC (£4.8M) and the Royal Society Wolfson Research Merit Award (£90k).
