  • Abstract
    A new simple method for formation of domain-inverted gratings in MgO:LiNbO3, i.e., 2-step voltage application under ultraviolet light, was proposed. A high quality grating of 19μm period was formed and applied to a waveguide quasi-phase-matched second-harmonic generation (QPM-SHG) device for pumping at 1.55μm wavelength. A SH power as high as 220mW was obtained for a pump power of 587mW. High applicability of the method to QPM device fabrication was demonstrated.
