All-Optical Logic Functions in a Bent Nonlinear Y-Junction Waveguide

Abstract

We propose and study all-optical logic gates, performing two input AND, OR and exclusive-OR (XOR) functions in a bent nonlinear Y-junction waveguide. The operation of the proposed device is based on the evolution of a nonlinear guided wave along a bent nonlinear waveguide. Since the characteristics of beam propagation depend on the nonlinearity, input power and bending angle of the waveguide, we could implement several all-optical logic functions (AND, OR and XOR) in the waveguide end and nonlinear medium, varying the above parameters.
