We identify and characterize the key physical parameters governing the beam steering, and show that the spatial resolution can be enhanced by the additional effect of nonlinear beam self-localization.© 2006 Optical Society of AmericaKeywords: Crystal lattices; Light interference; Light modulation; Nonlinear optics; Optical resolving power; Photorefractive materials; All-optical beam steering; Modulated photonic lattices; Self-localization; Spatial resolution; Light2005-11-2810.1364/OL.31.0014982016-06-14
