The nonlinear inverse synthesis (NIS) method, in which information is encoded directly onto
the continuous part of the nonlinear signal spectrum, has been proposed recently as a …

Nonlinear Fourier transform (NFT) and eigenvalue communication with the use of nonlinear
signal spectrum (both discrete and continuous) have been recently discussed as a …

In linear communication channels, spectral components (modes) defined by the Fourier
transform of the signal propagate without interactions with each other. In certain nonlinear …

Nonlinear Fourier transform (NFT) based transmission technique relies on the integrability of
the nonlinear Schrödinger equation (NLSE). However, the lossless NLSE is not directly …

A closed-form formula is derived, which corrects for the modulation format dependence of
the Gaussian noise (GN) model in the presence of inter-channel stimulated Raman …

A Gaussian noise (GN) model, precisely accounting for an arbitrary frequency dependent
signal power profile along the link, is presented. This allows accurate evaluation of the …

A closed-form model for the nonlinear interference (NLI) in Raman amplified links is
presented, the formula accounts for both forward (FW) and backward (BW) pumping …

We propose a method to quantitatively evaluate the improvement of the optical signal-to-
nose ratio () enabled by Raman pumping in hybrid Raman/erbium-doped fiber amplifiers …

Using the inverse scattering method known for solving partial differential equations such as
nonlinear Schrödinger equation, we analyse a fibre optic communication system which …

Using the integrable nonlinear Schrödinger equation (NLSE) as a channel model, we
describe the application of nonlinear spectral management for effective mitigation of all …
