LiNbO<SUB>3</SUB> waveguide devices for quasi-phase-matched nonlinear-optic wavelength conversion have beenstudied actively in many research groups. This paper reviews our research works of LiNbO<SUB>3</SUB> waveguide second harmonic generation (SHG) devices for implementation of compact short wavelength coherent lightsource, including descriptions of LiNbO<SUB>3</SUB> ferroelectric domain inversion by voltage application, SH blue/ultraviolet light generation with a normalized efficiency of 150%/W, enhancement of the efficiency utilizingresonant effect, generation of third harmonic wave of Nd: YAG laser light by cascading SHG and sumfrequencygeneration. Recent research topics of waveguide nonlinear-optic wavelength conversion devicesare also reviewed briefly.
