Methodologies

Guided modes (electric field profiles, effective indeces) have been computed with the help of Comsol Multiphysics (http://www.comsol.com/) commercial Maxwell solver (version 5.1).

The pulse propagation equation was solved with the help of Matlab, by using the well established split-step algorithm, full details of the algorithm are available in:

G.P. Agrawal, "Nonlinear Fiber Optics," 5th ed. (Academic Press, 2013).

Please find included the following:

##############################

1) A CSV spreadsheet: Fig1_data.csv

This file contains the guided mode profile (all components of the electric field) recorded on a rectangular grid in (x,y) plane.
The grid parameters are:
x: (-15:0.1:15) nm
y: (-15:0.1:15) nm

All electric field components are in SI units (V/m).
