Abstract

We explore dispersive and rectangular similariton solutions to the generalized nonlinear Schrödinger equation with varying dispersion, nonlinearity, gain, and source. The obtained similariton solutions are approximate but nevertheless highly accurate. As an application, we delineate the nonlinear compression of these similaritons for a dispersion-decreasing management profile. Also, for a periodic distributed amplification system, we demonstrate the formation of bound-state similaritons.
