Transmission systems based on the nonlinear Fourier transform (NFT) can potentially
address the limitations in transmission reach and throughput set forth by the onset of Kerr …

Nonlinear frequency division multiplexing (NFDM) communication systems that are based
on the nonlinear Fourier transform (NFT), have seen a rapid improvement in performance …

This paper investigates the capacity of signaling on the continuous spectrum (CS) of optical
fibers as defined by the nonlinear Fourier transform (NFT). The channel model of such NFT …

In this paper we propose the design of communication systems based on using periodic
nonlinear Fourier transform (PNFT), following the introduction of the method in the Part I. We …

We present a machine learning (ML) framework for designing desired signal power profiles
over the spectral and spatial domains in the fiber span. The proposed framework adjusts the …

Nonlinear frequency division multiplexing (NFDM) with the modulation of the nonlinear
Fourier spectrum (both discrete and continuous parts) has been recently considered as a …

We develop a novel broadband first-order Raman pump for use as a forward pump in
transmission experiments. Our results show significant signal relative intensity noise (RIN) …

The nonlinear Schr\" odinger equation (NSE) is well-known to model an ideal fiber-optic
communication channel. Even though the NSE is a nonlinear evolution equation, it can be …
