Here, we simulate the evolution of higher-order soliton pulses in a fiber.
The chromatic dispersion is calculated with the mode solver.
As there is significant third-order dispersion, the soliton evolution somewhat deviates from that expected for a fiber with only second-order dispersion – particularly if the initial pulse is rather short.
The simulation is done with an initial pulse which would correspond to a 4th-order soliton if there were no higher-order dispersion.
Figure 1 shows the evolution of the temporal shape.
Temporal profile of the pulse, as it evolves along the fiber.
The fiber length is taken to be just one soliton period (92 m).
Figure 2 shows the same as a color diagram.
Here, one sees more clearly that the initial pulse is not fully reproduced in the end.
This is due to higher-order dispersion of the fiber.
For longer pulses, this effect would be less pronounced.

Figure 3 shows the spectral evolution.
