Some potential schemes of controllable and steerable soliton-based optical switching in nonlinear waveguide arrays are discussed. For the first scheme it is suggested that unstable soliton modes be used to achieve easily steerable propagation of discrete bright and dark solitons. This is to avoid mode trapping by the
[1] Because the use of discrete solitons promises an efficient way to control multiport nonlinear switching in a system of many coupled waveguides, this field has been extensively explored theoretically.[2]-[5] More importantly, discrete solitons have also been generated experimentally in fabricated periodic waveguide

Abstract: We suggest an effective method for controlling nonlinear switching in arrays of weakly coupled optical waveguides. We demonstrate the digitized switching of a narrow input beam for up to eleven waveguides in the engineered waveguide arrays.
Stable stationary propagation[14],[15] and switching[16] of these discrete light bullets were reported recently. All considerations regarding discrete soliton switching assumed homogeneous waveguide arrays with constant[12] or smoothly varying[17] coupling between waveguides. However, in practical applications it is
13 Aug 2004 We demonstrate a simple concept for controlling nonlinear switching of discrete solitons in arrays of weakly coupled optical waveguides, for both cubic and quadratic nonlinear response. Based on the effective discrete nonlinear equations describing light propagation in the waveguide arrays in the
