    • Abstract


      It is well known that solitons in integrable systems recover their original profiles after their mutual collisions. This is not true in the case of optical fibre arrays, governed by a set of integrable coupled nonlinear Schrödinger (CNLS) equations. We consider the Manakov- and mixed-type `two-component' CNLS systems. The most important characteristics of these systems are:

      1. The polarizations of the two-component solitons are changed through their mutual collisions (Manakov system) and

      2. the energy (intensity) switching occurs through the head-on collision (mixed system).

      By placing the above solitons on the primary star graph (PSG), we see that soliton collisions give rise to interesting phase changes in PSG:


      These results will be applicable to network protocols using optical fibre arrays.
