Abstract
Uniform periodically poled domains were demonstrated in an insulator-sandwiched structure with z -cut lithium niobate wafers for an adhered ridge waveguide. Efficient quasi-phase-matched second harmonic generation was achieved in a mechanically defined ridge waveguide. Strong confinement in the waveguide produced second-harmonic-generation normalized conversion efficiency of 370%W cm2 in the 1.5 μm wavelength region.
