  bibo_abstract:
  - <jats:p>Lithium niobate and lithium tantalate are among the most widespread materials
    for nonlinear, integrated photonics. Mixed crystals with arbitrary Nb–Ta ratios
    provide an additional degree of freedom to not only tune materials properties,
    such as the birefringence but also leverage the advantages of the singular compounds,
    for example, by combining the thermal stability of lithium tantalate with the
    larger nonlinear or piezoelectric constants of lithium niobate. Periodic poling
    allows to achieve phase-matching independent of waveguide geometry and is, therefore,
    one of the commonly used methods in integrated nonlinear optics. For mixed crystals,
    periodic poling has been challenging so far due to the lack of homogeneous, mono-domain
    crystals, which severely inhibit domain growth and nucleation. In this work, we
    investigate surface-near (&amp;lt;1μm depth) domain inversion on x-cut lithium
    niobate tantalate mixed crystals via electric field poling and lithographically
    structured electrodes. We find that naturally occurring head-to-head or tail-to-tail
    domain walls in the as-grown crystal inhibit domain inversion at a larger scale.
    However, periodic poling is possible if the gap size between the poling electrodes
    is of the same order of magnitude or smaller than the average size of naturally
    occurring domains. This work provides the basis for the nonlinear optical application
    of lithium niobate tantalate mixed crystals.</jats:p>@eng
