We report the modulated Cerenkov radiations in a LiTaO3 waveguide with an annular domain structure. As a result of the continuous rotation symmetry of such a structure, the phase velocity of nonlinear polarization has a wide modulation tolerance. The reciprocal vectors which could be involved in the interaction had a threshold range associated with waveguide parameters. Our experimental results and simulations demonstrated that the radiation intensity had a close relationship with the overlapping between the pump and the radiated wave, which could be decreased by non-collinear reciprocal vectors.
