We demonstrate different designs of distributed Raman amplifiers and propose the
optimised configurations for both single and multi-fibre-span scenarios, which can provide …

Current fiber optic backhaul systems using linear transmission formats are expected to reach
the capacity limit due to the fiber's inherent Kerr nonlinearity in near future. Nonlinear …

Multi-soliton pulses are potential candidates for fiber optical transmission where the
information is modulated and recovered in the so-called nonlinear frequency domain. While …

Polarization-division multiplexing (PDM) with modulation in the nonlinear frequency domain
consisting of the discrete and/or continuous spectrum has been recently regarded as a …

We combine the nonlinear Fourier transform (NFT) signal processing with machine learning
methods for solving the direct spectral problem associated with the nonlinear Schrödinger …

Soliton communication, already widely studied some decades ago, got revitalized in the
recent years due to the growing interest in nonlinear Fourier transform based systems. In …

The non-linear Fourier transform may be considered an extension of Fourier analysis to
