On the Creation of Solitons in Amplifying Optical Fibers

Figure 5

Impact of gain: evolution of amplitude scaling parameter (orange), scaling parameter (blue), chirp (green), and soliton content (red) as calculated here (solid/dash-dotted lines) in comparison to numerical simulation (dots). (a) For the integrable NLSE system with and (b) with gain (), soliton appears at . Initial parameters: , , and .
