Nonlinear optical response of silica imposes a fundamental limit on the information transfer
capacity in optical fibers. Communication beyond this limit requires higher signal power and …

We scrutinize the concept of integrable nonlinear communication channels, resurrecting and
extending the idea of eigenvalue communications in a novel context of nonsoliton coherent …

What is the maximum rate at which information can be transmitted error-free in fibre–optic
communication systems? For linear channels, this was established in classic works of …

The nonlinear Fourier transform, which is also known as the forward scattering transform,
decomposes a periodic signal into nonlinearly interacting waves. In contrast to the common …

In this paper, we experimentally investigate high-order modulation over a single discrete
eigenvalue under the nonlinear Fourier transform (NFT) framework and exploit all degrees …

Long-haul optical communications based on nonlinear Fourier Transform have gained
attention recently as a new communication strategy that inherently embrace the nonlinear …

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 …

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