Polarization Drift Channel Model for Coherent Fibre-Optic Systems
Cristian B. Czegledi, Magnus Karlsson, Erik Agrell +1
A theoretical framework is introduced to model the dynamical changes of the state of polarization during transmission in coherent fibre-optic systems. The model generalizes the one…
Modeling of Nonlinear Signal Distortion in Fiber-Optical Networks
Pontus Johannisson, Erik Agrell
A low-complexity model for signal quality prediction in a nonlinear fiber-optical network is developed. The model, which builds on the Gaussian noise model, takes into account the…
Analytical Modeling of Nonlinear Propagation in a Strongly Dispersive Optical Communication System
Pontus Johannisson
Recently an analytical model was presented that treats the nonlinear signal distortion from the Kerr nonlinearity in optical transmission systems as additive white Gaussian noise.…
Nonlinear Bessel beams
Pontus Johannisson, Dan Anderson, Mietek Lisak +1
The effect of the Kerr nonlinearity on linear non-diffractive Bessel beams is investigated analytically and numerically using the nonlinear Schrödinger equation. The nonlinearity i…
Light bullets and optical collapse in vacuum
G. Brodin, L. Stenflo, D. Anderson +3
In quantum electrodynamics, photon--photon scattering can be the result of the exchange of virtual electron--positron pairs. Effectively, this gives rise to self-interaction terms…
