The nonlinear Fourier transform approach utilizes the symmetries of the nonlinear systems to find the solution of evolutional equations. Beyond straightforward mathematical application, it has been successfully demonstrated as a promising tool for digital signal processing in optical communication. Expanding the fibre-connectivity infrastructure for longer distances and higher powers, fibre nonlinearity becomes the main limiting factor. The NFT provides a nonlinearity-tolerant method for signal modulation, generalising the soliton-modulation concept, and reaching throughput value comparable with the modern fibre-optic transmission.
Panellists will talk about the powerful NFT method, exploiting the elegance of the mathematical trick, challenges of numerical implementations, achievements and perspectives.

,Pascal de KosterPascal de Koster (MSc.) obtained a BSc. double-degree in Applied Mathematics and Applied Physics and an MSc. degree in Applied Mathematics with a specialisation in Computational Science, both from Delft University of Technology. He is currently pursuing a PhD. at the Delft Center for Systems and Control, also at the TU Delft. His research focusses on identification of Lax-integrable systems and Nonlinear Fourier Transforms, which find applications in modelling, predicting and analysing nonlinear wave propagation, for example in shallow water canals and in deep ocean water, but also in optical fibres.
