We present an optical steering method in optical lattice with Kerr nonlinearity based on spatial phase modulation. By choosing proper phase modulation parameters, we can easily realize optical deflection, optical switching, and splitting of optical beams. The effect of lattice depth and lattice period on the optical steering is also discussed in detail.
