We designed a planar-waveguide quasi-phase-matched second-harmonic-generation device, which consists of a Y-cut periodically poled 5 mol. % MgO -doped LiNbO 3 core and SiO 2 claddings, that provided a 1.08 W green light with 30% conversion efficiency by using a 7 mm long sample at room temperature. The highest conversion efficiency of 49% at 0.88 W second-harmonic generation was attained by using an 18 mm long device.
