Abstract: The adaptive methodology of (purposefully, intentionally aperiodically) poling of an optical waveguide made in a nonlinear material substrate to achieve a continuous increase of overall nonlinear conversion efficiency with increase in the length of such waveguide. As a result of such poling, the variation of at least a waveguide thickness is compensated by adjusting the poling period along the waveguide to match the local momentum difference of the nonlinear process. For a second-harmonic generation, a near-ideal performance of the nonlinear energy conversion process was demonstrated even for a 21 mm long waveguide (with the SHG efficiency as high as 9415%/W and a 82.6% absolute power conversion efficiency). The adaptive poling methodology can also be applied to compensate other systematic inhomogeneity of a WG device in, for example, etching depth, diffusion depth, dose of lithographic exposure of the nonlinear material, and doping density across the nonlinear material substrate.
