  bibo_abstract:
  - "Many quantum optical applications in spectroscopy, communication and signal analysis
    rely on spectrally-engineered nonlinear optical interactions to target specific
    wavelengths or bandwidth. Here, in an established material platform like lithium
    niobate the achievable wavelength and bandwidth combinations are usually limited
    by the material’s dispersion and its birefringence. In this regard, mixed crystals
    of lithium niobate tantalate (LNT) promise a novel material platform, because
    they allow tuning the birefringence, which is central for type II phase matching
    devices. Crucially, LNT offers crystal  compositions without any birefringence,
    which still retain their second-order optical nonlinearity. Despite recent progress
    in the growth and fabrication of LNT, so far no works have investigated the unique
    properties of LNT for use in electro-optics, nonlinear or quantum optics. In this
    study, we explore nonlinear optical devices based on LNT for broad- and narrowband
    nonlinear optical interactions based on recently measured Sellmeier coefficients.
    Most interestingly, we find that compositions without birefringence allow the
    design of broadband, degenerate type II phase matching sources spanning the whole
    near- to mid-infrared range by only changing the poling period and pump wavelength.
    Such devices are not easily realizable in pure lithium niobate or lithium tantalate.
    This could potentially allow for\tmore flexible light sources and nonlinear devices
    in quantum metrology, quantum spectroscopy and quantum communication.@eng"
