    <title language="eng">Nonlinear coupling in discrete optical waveguide arrays with quadratic nonlinearity</title>
    <abstract language="eng">We demonstrate nonlinear coupling in a discrete optical system. This is achieved in waveguide arrays with quadratic nonlinearity, where the symmetries of the nonlinearly interacting waveguide modes are used to suppress the usually dominating nonlinear effects within individual waveguides. We derive a mathematical model to describe the nonlinear coupling in such waveguide arrays and show experimentally the profound effects of this nonlinear coupling mechanism on second-harmonic generation.</abstract>

    <title language="eng">Nonlinear Nearest-Neighbor Coupling in Quadratic Waveguide Arrays</title>
    <abstract language="eng">We investigate nonlinear coupling between neighboring waveguides in waveguide arrays with second-order nonlinearity. Using mode symmetries to suppress local nonlinearities, we experimentally show the profound effect of such nonlinear nearest-neighbor interactions on second-harmonic generation.</abstract>
