  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	more flexible light sources and nonlinear devices in quantum metrology, quantum spectroscopy and quantum communication.}},

  abstract     = {{Raman imaging, based on incoherent spontaneous Raman scattering (SR) or coherent techniques such as broadband coherent anti-Stokes Raman spectroscopy (BCARS), is a powerful tool for visualizing local lattice distortions. It can thus be employed, e.g., to identify and visualize ferroelectric (FE) domain walls (DWs). While SR-based DW imaging relies on small changes in the intensity or position of Raman peaks at the DW, BCARS measurements may detect DW signatures with a drastically increased contrast and orders of magnitude faster imaging speed. However, while SR-based contrasts can be predicted from existing models, the increased DW contrasts in BCARS remain poorly understood. In this work, we develop a first-principles approach for the simulation of CARS spectra to investigate the origin of this BCARS signal contrast at periodically poled stoichiometric lithium niobate (sPPLN) DWs. Combining these atomistic simulations with strain modeling allows us to explore how strain affects the CARS signal generation at FE DWs. We then apply polarization-sensitive BCARS to image sPPLN DWs for different polarization configurations. Our results reveal additional Raman peaks specific to the DWs across all investigated polarization combinations, yielding a strong DW-to-bulk contrast that enables in situ identification and localization of DWs in two-dimensional BCARS maps. This study demonstrates the practical utility of polarization-sensitive BCARS for fast DW imaging and provides fundamental insights into the BCARS contrast mechanism in FE materials, both in strained regions and in the unstrained bulk.}},

  abstract     = {{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.}},

  abstract     = {{The comprehensive description of both the electrical transport along conductive domain walls in lithium niobate single crystals and the charge injection at the interfacing metal electrodes, emerged to be a complex challenge. Recently, a heuristic evaluation allowed to postulate the “𝑅⁢2⁢𝐷⁢2
” equivalent-circuit model (consisting of two parallel resistor-diode pairs) to appropriately match the dc current-voltage (I-V) characteristics. Here, we carefully revisit the interfacial electrical behavior, i.e., the diode part of the equivalent circuit model, since many more processes beyond the diode-related electron hopping transport (HT) assumed so far, may concurrently occur, such as thermionic emission (TE), Fowler-Nordheim tunneling (FNT), space-charge limited conduction (SCLC), and others. The “𝑅⁢2⁢𝐷⁢2
” model thus needs to be generalized into an “𝑅⁢2⁢𝑋⁢2
” circuit model (with 𝑋
= HT, TE, FNT, SCLC, and others) to fit to the experimental data. Moreover, to check for the best I-V curve fitting to the different theories, we apply a higher-harmonic DW current-contribution analysis, i.e., an ac I-V inspection, that allows us to discriminate between all these possible models with much higher precision than from pure dc I-V curve fitting. Both the ac and dc analysis yield consistent results, finding that the FNT model accounts best for the domain-wall/electrode junctions investigated here.}},

  abstract     = {{<jats:p>Lithium niobate sees widespread use in nonlinear and quantum optical devices, such as for sum- and difference-frequency generation or spontaneous parametric downconversion. In lithium niobate waveguides, nonlinear optical processes are often limited by the so-called photorefractive effect, which limits the maximum input or output powers and impacts the nonlinear spectral response. Therefore, strategies for the management of photorefractive damage are a key consideration in device design. Usually, the photorefractive damage threshold, i.e., the maximal permissible operating power, can be increased by high-temperature operation of devices. This approach, however, is not applicable in cryogenic environments, which may be required for specialized applications. To better understand the impact of photorefraction in nonlinear optical applications, we study the impact of photorefraction on the phase-matching spectra of two nonlinear-optical sum-frequency generation experiments at (1) high temperatures and (2) cryogenic temperatures. Furthermore, we present an approach to reduce the impact of photorefraction, which is compatible with cryogenic operation. This comprises an auxiliary light source, propagating in the same waveguide, which is used to restore phase-matching spectra impacted by photorefraction, as well as reduce pyroelectric effects. Our work provides an alternative route to photorefraction management applicable to cryogenic environments, as well as in situations with tight energy budgets, such as space applications.</jats:p>}},
