This paper reviews and extends a method for the semi-analytical solution of the coupled linear differential equations that describe the linear mode coupling arising in few-mode fibers due to waveguide imperfections. The semi-analytical solutions obtained proved to be accurate when compared to numerical solution methods. These solutions were integrated into a multisection model with split-steps for...
This paper reviews our most recent results on mode-division multiplexing systems based on few-mode fibres with low differential mode delay, spanning from the fibre design optimization to the receiver memory dimensioning. First, the fibre refractive-index profile is optimized for low differential mode delay and low macro-bend losses. Afterwards, we present a semi-analytical model of the linear mode...
We mathematically analyze Kerr-induced fiber non-linearity in an optical communication system using mid-link optical phase conjugation and pre-dispersion. The derived analytical expressions are used to describe the system performance and show great matching with simulations. Furthermore, based on these expressions, we predict the performance of a transmission system and prove a 3dB improvement in...
Linear equalization performance for delay-managed few-mode links in the nonlinear regime with intermediate linear coupling is studied for the first time. Existing fibers can allow similar performance per mode to that of uncoupled single-mode propagation.
We report an investigation on the statistics of group delay for few-mode fibres operating in the weak and strong linear coupling regimes as well as in the intermediate coupling regime. A single expression linking the standard deviation of the group delay spread to the fibre linear mode coupling is validated for any coupling regime, considering up to six linearly polarized guided modes. Furthermore,...
