@article{37933, abstract = {{We present a time-over-threshold readout technique to count the number of activated pixels from an array of superconducting nanowire single photon detectors (SNSPDs). This technique places no additional heatload on the cryostat, and retains the intrinsic count rate of the time-tagger. We demonstrate proof-of-principle operation with respect to a four-pixel device. Furthermore, we show that, given some permissible error threshold, the number of pixels that can be reliably read out scales linearly with the intrinsic signal-to-noise ratio of the individual pixel response.}}, author = {{Tiedau, Johannes and Schapeler, Timon and Anant, Vikas and Fedder, Helmut and Silberhorn, Christine and Bartley, Tim}}, issn = {{1094-4087}}, journal = {{Optics Express}}, keywords = {{Atomic and Molecular Physics, and Optics}}, number = {{4}}, publisher = {{Optica Publishing Group}}, title = {{{Single-channel electronic readout of a multipixel superconducting nanowire single photon detector}}}, doi = {{10.1364/oe.383111}}, volume = {{28}}, year = {{2020}}, } @article{20156, author = {{Schapeler, Timon and Höpker, Jan Philipp and Bartley, Tim}}, issn = {{1094-4087}}, journal = {{Optics Express}}, title = {{{Quantum detector tomography of a 2×2 multi-pixel array of superconducting nanowire single photon detectors}}}, doi = {{10.1364/oe.404285}}, year = {{2020}}, } @article{26237, author = {{Luo, Kai-Hong and Ansari, Vahid and Massaro, Marcello and Santandrea, Matteo and Eigner, Christof and Ricken, Raimund and Herrmann, Harald and Silberhorn, Christine}}, issn = {{1094-4087}}, journal = {{Optics Express}}, title = {{{Counter-propagating photon pair generation in a nonlinear waveguide}}}, doi = {{10.1364/oe.378789}}, year = {{2019}}, } @article{26509, author = {{Tiedau, Johannes and Meyer-Scott, Evan and Nitsche, Thomas and Barkhofen, Sonja and Bartley, Tim J. and Silberhorn, Christine}}, issn = {{1094-4087}}, journal = {{Optics Express}}, title = {{{A high dynamic range optical detector for measuring single photons and bright light}}}, doi = {{10.1364/oe.27.000001}}, year = {{2019}}, } @article{9826, author = {{Tiedau, Johannes and Meyer-Scott, Evan and Nitsche, Thomas and Barkhofen, Sonja and Bartley, Tim and Silberhorn, Christine}}, issn = {{1094-4087}}, journal = {{Optics Express}}, title = {{{A high dynamic range optical detector for measuring single photons and bright light}}}, doi = {{10.1364/oe.27.000001}}, year = {{2019}}, } @article{11955, author = {{Li, Tianyou and Wei, Qunshuo and Reineke, Bernhard and Walter, Felicitas and Wang, Yongtian and Zentgraf, Thomas and Huang, Lingling}}, issn = {{1094-4087}}, journal = {{Optics Express}}, number = {{15}}, pages = {{21153--21162}}, title = {{{Reconfigurable metasurface hologram by utilizing addressable dynamic pixels}}}, doi = {{10.1364/oe.27.021153}}, volume = {{27}}, year = {{2019}}, } @article{10282, author = {{Lin, Zemeng and Huang, Lingling and Zhao, Ruizhe and Wei, Qunshuo and Zentgraf, Thomas and Wang, Yongtian and Li, Xiaowei}}, issn = {{1094-4087}}, journal = {{Optics Express}}, number = {{13}}, pages = {{18740--18750}}, title = {{{Dynamic control of mode modulation and spatial multiplexing using hybrid metasurfaces}}}, doi = {{10.1364/oe.27.018740}}, volume = {{27}}, year = {{2019}}, } @article{47946, author = {{Zhao, Jie and Rüsing, Michael and Mookherjea, Shayan}}, issn = {{1094-4087}}, journal = {{Optics Express}}, keywords = {{Atomic and Molecular Physics, and Optics}}, number = {{9}}, publisher = {{The Optical Society}}, title = {{{Optical diagnostic methods for monitoring the poling of thin-film lithium niobate waveguides}}}, doi = {{10.1364/oe.27.012025}}, volume = {{27}}, year = {{2019}}, } @article{26052, author = {{Luo, Kai Hong and Ansari, Vahid and Massaro, Marcello and Santandrea, Matteo and Eigner, Christof and Ricken, Raimund and Herrmann, Harald and Silberhorn, Christine}}, issn = {{1094-4087}}, journal = {{Optics Express}}, title = {{{Counter-propagating photon pair generation in a nonlinear waveguide}}}, doi = {{10.1364/oe.378789}}, year = {{2019}}, } @article{13900, author = {{Song, Xiaohong and Zuo, Ruixin and Yang, Shidong and Li, Pengcheng and Meier, Torsten and Yang, Weifeng}}, issn = {{1094-4087}}, journal = {{Optics Express}}, number = {{3}}, pages = {{2225--2234}}, title = {{{Attosecond temporal confinement of interband excitation by intraband motion}}}, doi = {{10.1364/oe.27.002225}}, volume = {{27}}, year = {{2019}}, } @article{9614, author = {{Eigner, Christof and Santandrea, Matteo and Padberg, Laura and Volk, Martin F. and Rüter, Christian E. and Herrmann, Harald and Kip, Detlef and Silberhorn, Christine}}, issn = {{1094-4087}}, journal = {{Optics Express}}, title = {{{Periodically poled ridge waveguides in KTP for second harmonic generation in the UV regime}}}, doi = {{10.1364/oe.26.028827}}, year = {{2018}}, } @article{9619, author = {{Ansari, V. and Roccia, E. and Santandrea, Matteo and Doostdar, M. and Eigner, Christof and Padberg, Laura and Gianani, I. and Sbroscia, M. and Donohue, J.

In a further step, a computational simulation is used to calculate the implantation range of carbon-ions and the corresponding defect density distribution. A comparison between the simulation and the experimental data indicates that the depth profile of the second-order effective nonlinear coefficient is directly connected to the defect density that is induced by the ion irradiation. Furthermore it can be demonstrated that the annealing treatment partially recovers the second-order optical susceptibility.}}, author = {{Spychala, Kai J. and Berth, Gerhard and Widhalm, Alex and Rüsing, Michael and Wang, Lei and Sanna, Simone and Zrenner, Artur}}, issn = {{1094-4087}}, journal = {{OPTICS EXPRESS}}, number = {{18}}, pages = {{21444----21453}}, title = {{{Impact of carbon-ion implantation on the nonlinear optical susceptibility of LiNbO3}}}, doi = {{10.1364/OE.25.021444}}, year = {{2017}}, } @article{54085, author = {{Tentrup, Tristan B.
