title: All-optical phase- and power-controlled switching in nonlinear waveguide junctions.
abstract: We propose and study a novel all-optical waveguide switching element made from a nonlinear symmetric junction. Nonlinear index changes break the symmetry of the structure and induce routing of the signal to one of two output ports. Power- and phase-controlled switching with a weak control signal are possible. The switching is insensitive to the precise value of either power or phase and to the structure parameters.
