Current-voltage (I-U) characteristics, recorded at variable temperatures from LiNbO3 (LNO) DWs, are clearly able to differentiate between these two contributions. Practically, they allow us to directly quantify the physical parameters relevant to the two mechanisms (a) and (b) mentioned above. These are, for example, the resistance of the DW, the saturation current, the ideality factor, and the Schottky barrier height of the electrode-DW junction. Furthermore, the activation energies needed to initiate the thermally activated electronic transport along the DWs can be extracted. In addition, we show that electronic transport along LNO DWs can be elegantly viewed and interpreted in an adapted semiconductor picture based on a double-diode, double-resistor equivalent-circuit model, the R2D2 model. Finally, our R2D2 model was checked for its universality by successfully fitting the I-U curves of not only z-cut LNO bulk DWs, but equally of z-cut thin-film LNO DWs, and of x-cut thin-film DWs as reported in literature.' article_number: '024007' article_type: original author: - first_name: Manuel full_name: Zahn, Manuel last_name: Zahn - first_name: Elke full_name: Beyreuther, Elke last_name: Beyreuther - first_name: Iuliia full_name: Kiseleva, Iuliia last_name: Kiseleva - first_name: Ahmed Samir full_name: Lotfy, Ahmed Samir last_name: Lotfy - first_name: Conor J. full_name: McCluskey, Conor J. last_name: McCluskey - first_name: Jesi R. full_name: Maguire, Jesi R. last_name: Maguire - first_name: Ahmet full_name: Suna, Ahmet last_name: Suna - first_name: Michael full_name: Rüsing, Michael id: '22501' last_name: Rüsing orcid: 0000-0003-4682-4577 - first_name: J.

Furthermore, it provides fundamental insight into the effects of dispersion on the biphoton state. Here, we show that a characteristic dependence of the width of the temporal interferogram can be exploited to obtain insights into the amount of second-order dispersion inside the interferometer and to retrieve actual and Fourier-limited ultrashort biphoton correlation times of around 100 fs. In the presented scheme, we simultaneously measure spectral and temporal interferograms at the output of an SU(1,1) interferometer based on an integrated broadband parametric down conversion source in a Ti:LiNbO3 waveguide. article_number: '020350' author: - first_name: Franz full_name: Roeder, Franz id: '88149' last_name: Roeder - first_name: René full_name: Pollmann, René id: '78890' last_name: Pollmann - first_name: Michael full_name: Stefszky, Michael id: '42777' last_name: Stefszky - first_name: Matteo full_name: Santandrea, Matteo id: '55095' last_name: Santandrea orcid: 0000-0001-5718-358X - first_name: Kai Hong full_name: Luo, Kai Hong id: '36389' last_name: Luo orcid: 0000-0003-1008-4976 - first_name: V. full_name: Quiring, V. last_name: Quiring - first_name: Raimund full_name: Ricken, Raimund last_name: Ricken - first_name: Christof full_name: Eigner, Christof id: '13244' last_name: Eigner orcid: https://orcid.org/0000-0002-5693-3083 - first_name: Benjamin full_name: Brecht, Benjamin id: '27150' last_name: Brecht orcid: '0000-0003-4140-0556 ' - first_name: Christine full_name: Silberhorn, Christine id: '26263' last_name: Silberhorn citation: ama: Roeder F, Pollmann R, Stefszky M, et al.

We used XRF analysis to determine the elemental composition of the crystals. The Neumann–Kopp rule provided essential data for the end members lithium niobate (LN) and lithium tantalate (LT). The heats of fusion of the end members, given by DTA measurements, are 103 kJ/mol at 1531 K for LN and 289 kJ/mol at 1913 K for LT. These values were used as input parameters to generate the data. This data served as the basis for calculating a phase diagram for LN-LT solid solutions. Finally, based on the experimental data and a thermodynamic solution model, the Calphad Factsage module optimized the phase diagram. We also generated thermodynamic parameters for Gibbs’ excess energy of the solid solution. A plot of the segregation coefficient as a function of Ta concentration was derived from the phase diagram. author: - first_name: Umar full_name: Bashir, Umar last_name: Bashir - first_name: Detlef full_name: Klimm, Detlef last_name: Klimm - first_name: Michael full_name: Rüsing, Michael id: '22501' last_name: Rüsing orcid: 0000-0003-4682-4577 - first_name: Matthias full_name: Bickermann, Matthias last_name: Bickermann - first_name: Steffen full_name: Ganschow, Steffen last_name: Ganschow citation: ama: Bashir U, Klimm D, Rüsing M, Bickermann M, Ganschow S.

We find that the rising edge as well as the amplitude of the electrical signal have the most dependence on photon number. Accurately measuring the rising edge while simultaneously measuring the voltage of the pulse amplitude maximizes the photon-number resolution of SNSPDs. Using an optimal basis of principal components, we show unambiguous discrimination between one- and two-photon events, as well as partial resolution up to five photons. This expands the use case of SNSPDs to photon-counting experiments, without the need of detector multiplexing architectures.\r\n \r\n \ \r\n \r\n \r\n \ Published by the American Physical Society\r\n \ 2024\r\n \r\n \ \r\n " article_number: '014024' author: - first_name: Timon full_name: Schapeler, Timon id: '55629' last_name: Schapeler orcid: 0000-0001-7652-1716 - first_name: Niklas full_name: Lamberty, Niklas last_name: Lamberty - first_name: Thomas full_name: Hummel, Thomas id: '83846' last_name: Hummel orcid: 0000-0001-8627-2119 - first_name: Fabian full_name: Schlue, Fabian id: '63579' last_name: Schlue - first_name: Michael full_name: Stefszky, Michael id: '42777' last_name: Stefszky - first_name: Benjamin full_name: Brecht, Benjamin id: '27150' last_name: Brecht orcid: '0000-0003-4140-0556 ' - first_name: Christine full_name: Silberhorn, Christine id: '26263' last_name: Silberhorn - first_name: Tim full_name: Bartley, Tim id: '49683' last_name: Bartley citation: ama: Schapeler T, Lamberty N, Hummel T, et al.

However, BCARS encounters spectral distortion due to a setup-dependent non-resonant background (NRB). This study assesses BCARS reproducibility through a round robin experiment using two distinct BCARS setups and crystalline materials with varying structural complexity, including diamond, 6H-SiC, KDP, and KTP. The analysis compares setup-specific NRB correction procedures, detected and NRB-removed spectra, and mode assignment. We determine the influence of BCARS setup parameters like pump wavelength, pulse width, and detection geometry and provide a practical guide for optimizing BCARS setups for solid-state applications. article_number: '112' article_type: original author: - first_name: Franz full_name: Hempel, Franz last_name: Hempel - first_name: Federico full_name: Vernuccio, Federico last_name: Vernuccio - first_name: Lukas full_name: König, Lukas last_name: König - first_name: Robin full_name: Buschbeck, Robin last_name: Buschbeck - first_name: Michael full_name: Rüsing, Michael id: '22501' last_name: Rüsing orcid: 0000-0003-4682-4577 - first_name: Giulio full_name: Cerullo, Giulio last_name: Cerullo - first_name: Dario full_name: Polli, Dario last_name: Polli - first_name: Lukas M. full_name: Eng, Lukas M. last_name: Eng citation: ama: 'Hempel F, Vernuccio F, König L, et al.

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 (<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. author: - first_name: Laura full_name: Bollmers, Laura id: '61375' last_name: Bollmers - first_name: Tobias full_name: Babai-Hemati, Tobias last_name: Babai-Hemati - first_name: Boris full_name: Koppitz, Boris last_name: Koppitz - first_name: Christof full_name: Eigner, Christof id: '13244' last_name: Eigner orcid: https://orcid.org/0000-0002-5693-3083 - first_name: Laura full_name: Padberg, Laura id: '40300' last_name: Padberg - first_name: Michael full_name: Rüsing, Michael id: '22501' last_name: Rüsing orcid: 0000-0003-4682-4577 - first_name: Lukas M. full_name: Eng, Lukas M. last_name: Eng - first_name: Christine full_name: Silberhorn, Christine id: '26263' last_name: Silberhorn citation: ama: Bollmers L, Babai-Hemati T, Koppitz B, et al.
