Abstract
The bright soliton solutions of the mixed coupled nonlinear Schrodinger equations with two
components (2-CNLS) with linear self- and cross-coupling terms have been obtained by identifying a
transformation that transforms the corresponding equation to the integrable mixed 2-CNLS equations.
The study on the collision dynamics of bright solitons shows that there exists periodic energy
switching, due to the coupling terms. This periodic energy switching can be controlled by the new type
of shape changing collisions of bright solitons arising in a mixed 2-CNLS system, characterized by
intensity redistribution, amplitude dependent phase shift, and relative separation distance. We also
point out that this system exhibits large periodic intensity switching even with very small linear selfcoupling strengths.
