The analytical solutions were directly obtained from the coupled nonlinear Schrodinger equations. The transmission characteristics of first order solitons obtained by the analytical procedure agrees well with the results from numerical analysis. In addition, the analysis show the existence of soliton eigenstates, in the three core nonlinear fiber coupler, where no coupling between the fibers was observed. (C) 1998 Elsevier Science B.V.
