title: Coupling induced anomalous group velocity dispersion in nonlinear arrays of silicon photonic wires.
abstract: We demonstrate that the group velocity dispersion (GVD) of the supermodes in a small array of silicon photonic wires can differ dramatically from the single wire GVD. This enables soliton propagation and modulational instability to be seen at wavelengths where single wires have strongly normal GVD.
