Machine learning enabled digital compensation of phase-to-amplitude distortion in fibre-optical parametric amplifier based transmission links

Published in The European Optical Society Annual Meeting (EOSAM) 2023, Dijon, France, 2023

We numerically demonstrate an advanced digital signal processing method for compensating the phase-to-amplitude distortion conversion caused by the interaction of the phase noise induced by pump dithering with the dispersive fibre channel in fibre-optical parametric amplifier based transmission systems.

Digital signal processing for optical phase conjugation assisted coherent systems

Published in 23rd International Conference on Transparent Optical Networks (ICTON), Bucharest, Romania, 2023

We review our recent progress in the development of digital signal processing techniques to mitigate the impact of the phase modulation of the pump source on coherent optical systems deploying fibre-based optical phase conjugation devices.

Machine learning enabled compensation of phase-to-amplitude distortion in OPC systems

Published in Conference on Lasers and Electro-Optics (CLEO) 2023, San Jose, California, USA, 2023

We numerically demonstrate a digital signal processing method for compensating the phase-to-amplitude distortion caused by the interaction of imperfect counter-phasing pump dithering with the dispersive fibre channel in optical phase conjugated transmission systems. By using a machine learning algorithm assisted by the blind phase search method, we have shown significant bit error rate improvement on a 28 Gbaud 16-QAM signal over long transmission lengths.
