Manipulating the Propagation of Solitons with Solid-Core Photonic Bandgap Fibers

Figure 7

Left axis: evolution of the soliton central wavelength with fiber length calculated by integration of the GNLSE (black line) and with (5) in the case of the Gordon model (red line). Right axis: evolution of the 𝑅 ratio defined by (8) with soliton wavelength.
