The technique makes use of the fact that the intensity or frequency of certain phonons is strongly influenced by the presence of domain walls. Although the method is used frequently, the underlying mechanism responsible for the changes in the spectra is not fully understood. This inhibits deeper analysis of domain structures based on this method. Two different models have been proposed. However, neither model completely explains all observations. In this work, we have systematically investigated domain walls in different scattering geometries with Raman spectroscopy in the common ferroelectric materials used in integrated optics, i.e., KTiOPO4, LiNbO3, and LiTaO3. Based on the two models, we can demonstrate that the observed contrast for domain walls is in fact based on two different effects. We can identify on the one hand microscopic changes at the domain wall, e.g., strain and electric fields, and on the other hand a macroscopic change of selection rules at the domain wall. While the macroscopic relaxation of selection rules can be explained by the directional dispersion of the phonons in agreement with previous propositions, the microscopic changes can be explained qualitatively in terms of a simplified atomistic model.}}, author = {{Rüsing, Michael and Neufeld, Sergej and Brockmeier, Julian and Eigner, Christof and Mackwitz, P. and Spychala, K. and Silberhorn, Christine and Schmidt, Wolf Gero and Berth, Gerhard and Zrenner, Artur and Sanna, S.}}, issn = {{2475-9953}}, journal = {{Physical Review Materials}}, number = {{10}}, publisher = {{American Physical Society (APS)}}, title = {{{Imaging of 180∘ ferroelectric domain walls in uniaxial ferroelectrics by confocal Raman spectroscopy: Unraveling the contrast mechanism}}}, doi = {{10.1103/physrevmaterials.2.103801}}, volume = {{2}}, year = {{2018}}, } @article{9638, author = {{Meyer-Scott, Evan and Prasannan, Nidhin and Eigner, Christof and Quiring, Viktor and Donohue, John M. and Barkhofen, Sonja and Silberhorn, Christine}}, issn = {{1094-4087}}, journal = {{Optics Express}}, title = {{{High-performance source of spectrally pure, polarization entangled photon pairs based on hybrid integrated-bulk optics}}}, doi = {{10.1364/oe.26.032475}}, year = {{2018}}, } @article{9679, author = {{Stefszky, Michael and Ricken, R and Eigner, Christof and Quiring, V and Herrmann, Harald and Silberhorn, Christine}}, issn = {{2040-8978}}, journal = {{Journal of Optics}}, title = {{{High-power waveguide resonator second harmonic device with external conversion efficiency up to 75%}}}, doi = {{10.1088/2040-8986/aac1d5}}, year = {{2018}}, } @article{21029, author = {{Allgaier, Markus and Ansari, Vahid and Eigner, Christof and Quiring, Viktor and Ricken, Raimund and Donohue, John Matthew and Czerniuk, Thomas and Aßmann, Marc and Bayer, Manfred and Brecht, Benjamin and Silberhorn, Christine}}, issn = {{0003-6951}}, journal = {{Applied Physics Letters}}, title = {{{Streak camera imaging of single photons at telecom wavelength}}}, doi = {{10.1063/1.5004110}}, volume = {{112}}, year = {{2018}}, } @inproceedings{40388, author = {{Luo, Kai Hong and Brauner, Sebastian and Eigner, Christof and Sharapova, Polina and Ricken, Raimund and Meier, Torsten and Herrmann, Harald and Silberhorn, Christine}}, booktitle = {{Conference on Lasers and Electro-Optics}}, isbn = {{978-1-943580-42-2}}, location = {{San Jose, California United States}}, publisher = {{OSA}}, title = {{{Monolithically Integrated Hong-Ou-Mandel Experiment in LiNbO3}}}, doi = {{10.1364/cleo_qels.2018.fm1g.3}}, year = {{2018}}, } @article{9615, author = {{Allgaier, Markus and Ansari, Vahid and Sansoni, Linda and Eigner, Christof and Quiring, Viktor and Ricken, Raimund and Harder, Georg and Brecht, Benjamin and Silberhorn, Christine}}, issn = {{2041-1723}}, journal = {{Nature Communications}}, title = {{{Highly efficient frequency conversion with bandwidth compression of quantum light}}}, doi = {{10.1038/ncomms14288}}, year = {{2017}}, } @article{9618, author = {{Stefszky, Michael and Ricken, R. and Eigner, Christof and Quiring, V. and Herrmann, Harald and Silberhorn, Christine}}, issn = {{2331-7019}}, journal = {{Physical Review Applied}}, title = {{{Waveguide Cavity Resonator as a Source of Optical Squeezing}}}, doi = {{10.1103/physrevapplied.7.044026}}, year = {{2017}}, } @article{9681, author = {{Volk, Martin F. and Rüter, Christian E. and Santandrea, Matteo and Eigner, Christof and Padberg, Laura and Herrmann, Harald and Silberhorn, Christine and Kip, Detlef}}, issn = {{2159-3930}}, journal = {{Optical Materials Express}}, title = {{{Fabrication of low-loss Rb-exchanged ridge waveguides in z-cut KTiOPO_4}}}, doi = {{10.1364/ome.8.000082}}, year = {{2017}}, } @inproceedings{9682, author = {{Brecht, Benjamin and Lazo-Arjona, O. and Kaczmarek, K.
