We report the observation of large self-deflection of 2-D bright photorefractive solitons in LiNbO3 crystal under a dc applied field. Beam deflection as large as 300 µm after a 7 mm propagation distance is reported, leading to formation of curved 2-D waveguides. We attribute this large deflection to the low level of impurity acceptors present in the samples, as confirmed by numerical results from a time-dependent photorefractive model.
