Nonlinear Landau-Zener Tunnelling in Coupled Waveguide Arrays

Abstract

The possibility of direct observation of Nonlinear Landau-Zener tunnelling effect with a device consisting of two waveguide arrays connected with a tilted reduced refractive index barrier is discussed. Numerical simulations on this realistic setup are interpreted via simplified double well system and different asymmetric tunnelling scenarios were predicted just varying injected beam intensity.
