  - Understanding and controlling the optical properties of lithium niobate tantalate
    solid solutions (LiNb1−xTaxO3, 0 ≤ x ≤ 1) is essential for their use in integrated
    quantum and nonlinear photonics. This material system allows for composition-dependent
    tuning of key optical parameters such as refractive indices and birefringence.
    While lithium niobate (LiNbO3, x = 0) and lithium tantalate (LiTaO3, x = 1) are
    well characterized, reliable dispersion data for intermediate compositions remain
    scarce, limiting accurate modeling and refractive index engineering. Here, we
    address this gap by experimentally determining the ordinary and extraordinary
    refractive indices of LiNb1−xTaxO3 over the spectral range of 405 − 1550 nm using
    an interferometric technique. As a result, composition-dependent refractive index
    dispersion and Sellmeier coefficients are derived and discussed in relation to
    previous studies and structural aspects. In particular, a monotonic decrease of
    the ordinary refractive index with increasing Tantalum concentration is observed.
    The present Sellmeier coefficients further allow discussion of zero birefringence
    dispersion and its composition dependence in lithium niobate tantalate.@eng
