Generating the fiber structures

Here we create the different fiber design that we want to explore

wavelength_list = numpy.linspace(500e-9, 3000e-9, 100)
data = []
for wavelegnth in wavelength_list:
    smf28 = load_fiber(fiber_name='SMF28', wavelength=wavelegnth)
    dispersion = smf28.get_effective_index(mode=LP01)
    data.append(dispersion)


figure, ax = plt.subplots(1, 1)

ax.set(
    title='Mode fields for vectorial mode if x-direction',
    xlabel=r'Wavelength [$\mu m$]',
    ylabel='Group index',
)


ax.plot(wavelength_list, data)

plt.show()
