## Fast Single-Mode Fiber Nonlinearity Monitoring

### An Experimental Comparison Between Split-Step and Nonlinear Fourier Transform-Based Methods

We experimentally investigate the problem of monitoring the Kerr-nonlinearity coefficient $\gamma$ from transmitted and received data for a single-mode fiber link of 1600 km length. We compare the accuracy and speed of three different approaches. First, a standard split-step F ...

## Nonlinear frequency division multiplexing with b-modulation

### Shifting the energy barrier

The recently proposed b-modulation method for nonlinear Fourier transform-based fiber-optic transmission offers explicit control over the duration of the generated pulses and therewith solves a longstanding practical problem. The currently used b-modulation however suffers fro ...

## Identification of Spines in Nonlinear Fourier Spectra for the Periodic Nonlinear Schrödinger Equation

### Internship WI5118 - Report

The nonlinear Fourier transform for the focusing periodic nonlinear Schrodinger equation is investigated. This paper is focused on the approximation of the spines in the nonlinear spectrum using results from Floquet theory. Algorithms for the numerical comput ...
