Download the modes

Click on modes.npz to download the results as a numpy file or click modes.mat to download as a Matlab file.

To retrieve the data in Python:

import numpy as np

data = np.load('modes.npz')
n_modes = data['n_modes']
n_points = data ['n_points']
# matrix of mode profiles
mode_profiles = data['profiles'] 
# propagation constants
betas = data['betas']

# Profile of the i-th mode
i = 5
field = mode_profiles[...,i].reshape([n_points]*2)
