Despite the effects of pyroelectricity and photorefraction, the spectral properties match our theoretical model.

However, integrating single-photon detectors requires cryogenic operating temperatures, since the best performing detectors are based on narrow superconducting wires. While previous studies have demonstrated the operation of quantum light sources and electro-optic modulators in LiNbO<jats:sub>3</jats:sub> at cryogenic temperatures, the thermal transition between room temperature and cryogenic conditions introduces additional effects that can significantly influence device performance. In this paper, we investigate the generation of pyroelectric charges and their impact on the optical properties of lithium niobate waveguides when changing from room temperature to 25 K, and vice versa. We measure the generated pyroelectric charge flow and correlate this with fast changes in the birefringence acquired through the Sénarmont-method. Both electrical and optical influence of the pyroelectric effect occur predominantly at temperatures above 100 K.</jats:p>","lang":"eng"}],"status":"public","_id":"51356","project":[{"_id":"171","name":"TRR 142; TP C07: Hohlraum-verstärkte Parametrische Fluoreszenz mit zeitlicher Filterung unter Verwendung integrierter supraleitender Detektoren"}],"user_id":"56843","keyword":["General Earth and Planetary Sciences","General Environmental Science"],"article_number":"015402","language":[{"iso":"eng"}]},{"funded_apc":"1","file_date_updated":"2023-04-18T05:50:19Z","article_type":"original","user_id":"30525","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"}],"project":[{"_id":"53","name":"TRR 142: TRR 142"},{"name":"TRR 142 - B: TRR 142 - Project Area B","_id":"55"},{"_id":"170","name":"TRR 142 - B09: TRR 142 - Subproject B09"},{"_id":"171","name":"TRR 142 - C07: TRR 142 - Subproject C07"},{"_id":"56","name":"TRR 142 - C: TRR 142 - Project Area C"}],"_id":"44044","status":"public","type":"journal_article","main_file_link":[{"open_access":"1","url":"https://pubs.acs.org/doi/full/10.1021/acs.nanolett.2c04980"}],"doi":"10.1021/acs.nanolett.2c04980","author":[{"last_name":"Geromel","full_name":"Geromel, René","first_name":"René"},{"first_name":"Philip","last_name":"Georgi","full_name":"Georgi, Philip"},{"last_name":"Protte","full_name":"Protte, Maximilian","id":"46170","first_name":"Maximilian"},{"first_name":"Shiwei","last_name":"Lei","full_name":"Lei, Shiwei"},{"first_name":"Tim","full_name":"Bartley, Tim","id":"49683","last_name":"Bartley"},{"first_name":"Lingling","full_name":"Huang, Lingling","last_name":"Huang"},{"id":"30525","full_name":"Zentgraf, Thomas","orcid":"0000-0002-8662-1101","last_name":"Zentgraf","first_name":"Thomas"}],"volume":23,"date_updated":"2023-05-12T11:17:51Z","oa":"1","citation":{"chicago":"Geromel, René, Philip Georgi, Maximilian Protte, Shiwei Lei, Tim Bartley, Lingling Huang, and Thomas Zentgraf. “Compact Metasurface-Based Optical Pulse-Shaping Device.” <i>Nano Letters</i> 23, no. 8 (2023): 3196–3201. <a href=\"https://doi.org/10.1021/acs.nanolett.2c04980\">https://doi.org/10.1021/acs.nanolett.2c04980</a>.","ieee":"R.

However, these devices are only able to compensate for a part of the dispersion (second-order dispersion). Here, we present a compact pulse-shaping device that uses plasmonic metasurfaces to apply an arbitrarily designed spectral phase delay allowing for a full dispersion control. Furthermore, with specific phase encodings, this device can be used to temporally reshape the incident laser pulses into more complex pulse forms such as a double pulse. We verify the performance of our device by using an SHG-FROG measurement setup together with a retrieval algorithm to extract the dispersion that our device applies to an incident laser pulse.","lang":"eng"}],"publication":"Nano Letters","title":"Compact Metasurface-Based Optical Pulse-Shaping Device","date_created":"2023-04-18T05:47:22Z","publisher":"American Chemical Society (ACS)","year":"2023","issue":"8","quality_controlled":"1"},{"user_id":"56843","department":[{"_id":"15"},{"_id":"230"},{"_id":"623"}],"project":[{"name":"TRR 142; TP C07: Hohlraum-verstärkte Parametrische Fluoreszenz mit zeitlicher Filterung unter Verwendung integrierter supraleitender Detektoren","_id":"171"}],"_id":"46468","language":[{"iso":"eng"}],"article_number":"023701","type":"journal_article","publication":"Physical Review A","status":"public","author":[{"orcid":"0000-0001-6624-7098","last_name":"Lange","id":"56843","full_name":"Lange, Nina Amelie","first_name":"Nina Amelie"},{"orcid":"0000-0001-7652-1716","last_name":"Schapeler","id":"55629","full_name":"Schapeler, Timon","first_name":"Timon"},{"first_name":"Jan Philipp","full_name":"Höpker, Jan Philipp","id":"33913","last_name":"Höpker"},{"first_name":"Maximilian","id":"46170","full_name":"Protte, Maximilian","last_name":"Protte"},{"first_name":"Tim","id":"49683","full_name":"Bartley, Tim","last_name":"Bartley"}],"date_created":"2023-08-10T07:34:54Z","volume":108,"publisher":"American Physical Society (APS)","date_updated":"2025-12-15T09:24:16Z","doi":"10.1103/physreva.108.023701","title":"Degenerate photons from a cryogenic spontaneous parametric down-conversion source","issue":"2","publication_status":"published","publication_identifier":{"issn":["2469-9926","2469-9934"]},"citation":{"mla":"Lange, Nina Amelie, et al. “Degenerate Photons from a Cryogenic Spontaneous Parametric Down-Conversion Source.” <i>Physical Review A</i>, vol. 108, no. 2, 023701, American Physical Society (APS), 2023, doi:<a href=\"https://doi.org/10.1103/physreva.108.023701\">10.1103/physreva.108.023701</a>.","bibtex":"@article{Lange_Schapeler_Höpker_Protte_Bartley_2023, title={Degenerate photons from a cryogenic spontaneous parametric down-conversion source}, volume={108}, DOI={<a href=\"https://doi.org/10.1103/physreva.108.023701\">10.1103/physreva.108.023701</a>}, number={2023701}, journal={Physical Review A}, publisher={American Physical Society (APS)}, author={Lange, Nina Amelie and Schapeler, Timon and Höpker, Jan Philipp and Protte, Maximilian and Bartley, Tim}, year={2023} }","short":"N.A.
