Blocking and routing discrete solitons in two-dimensional networks of nonlinear waveguide arrays

Summary form only given. We show that discrete solitons propagating in two-dimensional waveguide array networks can provide a rich environment for all-optical data processing applications. We demonstrate that such arrays can effectively act like soliton wires along which these self-trapped beams can travel. In addition, by using vector/incoherent interactions at the network junctions, these soliton signals can be routed at will along specific pathways. Therefore, this family of solitons can be navigated anywhere within a two-dimensional network of nonlinear waveguides.
