Electrodynamics of a simple device, which is nonlinear coupler, is considered. In this case, signs of the refraction index of coupled waveguides assumed to be opposite. It is demonstrated that opposite directionality of the phase velocity and the energy flow in the negative refraction index channel facilitates an effective feedback mechanism that leads to optical bistability and gap soliton formation.
