Abstract.
By means of the similarity transformation, we obtain exact bright and dark similariton-pair solutions in nonlinear waveguides for the generalized nonlinear Schrödinger equation exhibiting spatial inhomogeneity, inhomogeneous nonlinearity and gain or loss at the same time. Then we investigate the interaction behaviors of these solitonic similaritons in a periodic distributed amplification system.
