| Abstract: | By means of the similarity transformation, we obtain exact bright
and dark similariton-pair solutions in nonlinear waveguides for
the generalized nonlinear Schr?dinger 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. |
