Soliton collisions with shape change by intensity redistribution in mixed coupled nonlinear Schrödinger equations

Kanna, T; Lakshmanan, M; Tchofo Dinda, P; Akhmediev, Nail


A different kind of shape changing (intensity redistribution) collision with potential application to signal amplification is identified in the integrable N-coupled nonlinear Schrödinger (CNLS) equations with mixed signs of focusing- and defocusing-type nonlinearity coefficients. The corresponding soliton solutions for the N=2 case are obtained by using Hirota’s bilinearization method. The distinguishing feature of the mixed sign CNLS equations is that the soliton solutions can both be singular...[Show more]
