We present a blindly adaptive nonlinear channel equalizer that effectively compensates nonlinearity in SSB-PAM4 transceiver components.

The new concept of filtering the nonlinear spectrum of signal in order to reduce the noise-induced signal degradation is introduced and, as the result, the performance improvement at high powers is

Multi-soliton pulses, as special solutions of the Nonlinear Schrodinger Equation (NLSE), are a potential candidate for data modulation in optical fiber communication.

Fiber-optic communication systems are nowadays facing serious challenges due to fast growing demand on capacity from various new applications and services.

Joint decision on eigenvalue patterns and on corresponding amplitudes was experimentally demonstrated using the discrete part of the nonlinear Fourier transform of a high power two symbol QPSK burs

A mathematical tool for calculating the nonlinear Fourier transform (NFT) of a time-domain signal is the Ablowitz-Ladik iteration.

Record data rate of 50 Gb/s in nonlinear frequency division multiplexing (NFDM) transmission is experimentally demonstrated using 64 overlapping orthogonal 0.5 Gbaud channels with 64 QAM format, sh

In this paper, we review the recent progress of Nonlinear Frequency Division Multiplexing (NFDM) transmission research.

In this tutorial the basics of nonlinear frequency division multiplexing (NFDM) are revisited, modulation of parts of the nonlinear spectrum will be discussed and algorithmic and experimental eleme
