We present an analytical investigation of the propagation and the
switching of fundamental solitons in a three-core nonlinear fiber
coupler with a variational method using the Lagrangian density
formulation. The analytical solutions were obtained directly from the
coupled nonlinear Schrodinger equations. The transmission
characteristics of first order solitons obtained by the analytical
procedure agree well with the results from numerical analysis. Three
different geometries for the nonlinear three-core directional coupler
were studied. Taking into account the length of the coupler and the
critical power a comparative study between these geometries was done.
