  text: "We report the fabrication of periodically poled domain patterns in x-cut
    lithium niobate thin-film.\r\nHere, thin films on insulator have drawn particular
    attention due to their intrinsic waveguiding\r\nproperties offering high mode
    confinement and smaller devices compared to in-diffused waveguides\r\nin bulk
    material. In contrast to z-cut thin film lithium niobate, the x-cut geometry does
    not\r\nrequire back electrodes for poling. Further, the x-cut geometry grants
    direct access to the largest\r\nnonlinear and electro-optical tensor element,
    which overall promises smaller devices. The domain\r\ninversion was realized via
    electric field poling utilizing deposited aluminum top electrodes on a\r\nstack
    of LN thin film/SiO2 layer/Bulk LN, which were patterned by optical lithography.
    The periodic\r\ndomain inversion was verified by non-invasive confocal second
    harmonic microscopy. Our\r\nresults show domain patterns in accordance to the
    electrode mask layout. The second harmonic signatures\r\ncan be interpreted in
    terms of spatially, overlapping domain filaments which start their\r\ngrowth on
    the þz side."
