Waveguides coupling have been widely studied; however, nanowaveguides of high refraction index contrast open the opportunity of studying the nonlinear dynamics of coupled waveguides, in particular those filled with metallic nanaoparticles composites. Those composites show a Quantum Mechanical Kerr Nonlinearity and a classical field amplitude nonlinearity that are compared by using a iterative WKB to introduce the field nonlinearity and based in the ensuing M matrix. The produced nonlinear supermodes show a confinement of the pulse in the waveguides and a breaking of the coupling at small and large core waveguides. © 2009 SPIE.
