By using carbon ion implantation and rotating blade dicing, ridge waveguides have been produced in periodically poled MgO doped congruent LiNbO3 crystal. The guiding properties at wavelength of near-infrared waveband have been investigated. The quasi-phasematched second harmonic generation in the ridge waveguides has been characterized. The depth profile of the d(33) nonlinear coefficient in the implanted region has been evaluated by the reflected second-harmonic generation from angle-lapped samples.
