The deflection of light reported by Müller et al. in lithium niobate [Appl. Phys. B 78, 367-370] and lithium tantalate [Appl. Optics 43 (34), 6344-6347] under electric field originates from refraction at domain-walls, like in ferroelastics. In ferroelectrics the optical discontinuity takes place at domain-walls as a consequence of the electro-optic effect. The theoretical deflection angle calculated from Snell's law is proportional to the square root of the electric field and matches the experimental results reported by Müller et al. for lithium niobate. The finite domain-wall thickness mentioned by the authors is not involved in the deflection phenomenon.
