This repository provides helper functions and models for nonlinear performance prediction of ultra-wideband coherent optical communication systems.
In particular, this repository provides an implementation of the Gaussian Noise (GN) model in the presence of inter-channel stimulated Raman scattering (ISRS) in closed-form. This enables real-time performance estimation in point-to-point as well as in mesh optical network transmission. The implementation is based on the results published in our paper:
[1] D. Semrau, R. I. Killey, P. Bayvel, "A Closed-Form Approximation of the Gaussian Noise Model in the Presence of Inter-Channel Stimulated Raman Scattering, " J. Lighw. Technol., Early Access, DOI: 10.1109/JLT.2019.2895237, Jan. 2019.
The implementation of the ISRS GN model in closed-form can be found in the ISRS GN model function below, both in Matlab and in Python.
To help readers apply the implementation, the example code below uses the ISRS GN model function to reproduce the results in [1]. For a full documentation of the required syntax, please see here.
