Effect of Phase Shift in Shape Changing Collision of Solitons in Coupled Nonlinear Schroedinger Equations
Soliton interactions in systems modelled by coupled nonlinear Schroedinger
(CNLS) equations and encountered in phenomena such as wave propagation in
optical fibers and photorefractive media possess unusual features : shape
changing intensity redistributions, amplitude dependent phase shifts and
relative separation distances. We demonstrate these properties in the case of
integrable 2-CNLS equations. As a simple example, we consider the stationary
two-soliton solution which is equivalent to the so-called partially coherent
soliton (PCS) solution discussed much in the recent literature.Comment: 11 pages, revtex4,Two eps figures. European Journal of Physics B (to
